I'm not entirely new to Krita. I've been using it for a few months now, but only recently has it started to mess up some save files and I don't understand why. And before I forget I use Windows 7.

Let me make it perfectly plain, I don't fully understand what the true issue is. Nor do I know how to explain it without some pictures (which I have thankfully illustrating my problem). When did my problem start occurring? Sometime after the 25h of May. And is still happening to this day. It's not even consistent either. Sometimes it messes up my work more than others. Without beating around the bush too much, here are the images. We shall start off with the faulty images in question.


All the read circles are highlights of the areas Krita has messed up (oh and don't mind the watermark). This is a direct result of me trying to open the file in Krita after saving and exporting it. I only have one theory on what's causing this. If I leave Krita on and let my computer go to sleep (with the file on it) and wake my computer up again and try to open the file up (after saving it before I let my computer fall asleep of course) it just does this..... whatever it is you see above. However I don't think this is sole the reason. And would like any input on what could be the real reason. Moving along, here is the same car but in a png (because exporting it into a png before closing the file entirely doesn't mess up the lines).


See? Completely fine. Want to see what it looks like in Krita though? Here you go.


Once again, all the red bits are highlights of all the imperfections in the file once I open up the ,kra file. I have more of them because not only do the ends of the lines move, but the entire lines move as well. Creating ugly "rifts" in the paint (so to speak). And this isn't the only car this has happened to. Coming up is a small gallery of cars with problems, and what they look like as PNGs (prior to closing Krita when I was making these files).

It'll go like this. Non-colored image, Colored image, PNG (the PNG being the image that's fine).








There are more cars with the same problem. But I think you get the picture (pun intended). Do I know what's causing this? No. What I can tell you is that it started with that drift car (the blue car going sideways). And I can't replicate the circumstances that caused this problem because I don't know what I did to cause it during the making of that car. However, there are cars that don't share this problem. So once again, here are cars that are completely fine even after opening them (even today, despite this problem still going on). And once again they'll go from non-colored to colored to PNG.










And there you have it. If any of you know why this is happening then do please reply to this thread and share your thoughts. As I can't continue my work confidently knowing that this is a problem that is still occurring.

This is the method I use to make these cars: https://www.youtube.com/watch?v=ohwGIrfuoIA

Don't know if that'll be useful or not but hopefully it'll give someone a clue as to how and why this is happening (I didn't make the cars above in GIMP but it's the same method as in the video).

hey. Thanks for all the screenshots and explanations.

I do see you are using a lot of vector layers in your document. My only guess is somehow when krita is saving, it is not storing the X and Y positions correctly, so it might be a fraction of a pixel off when it is saving and creating those problems.

We are in the middle of redoing our vector tools and converting them to SVG, so any fixes we do would have to be as part of that work. Can you test out our pre-alpha version of 4.0 and test to see if it is still happening. There was a lot of work done to vector tools, so it is possible that it is fixed in this version. You can get the download link here...

It is possible that it is fixed. If it isn't, we can take a look at your file and try to see what is causing the problem

Np! Frankly the pictures illustrate what I'm saying far better than I could ever describe lol.

It'll probably take me at least two days before I come back with a reply. as I'll try to verify if my theory will work. I'll start by creating 10 "untainted" images and see if any problems start arising (I'll do more if it goes quickly). And then I'll do 10 "tainted" images. By which I mean I'll create an image, save it, let my computer fall asleep and then save it again. By which time I'll re-open the possibly tainted image and see if any imperfections occur. I'm not certain if this phenomenon causes the imperfections but if it starts before the "tainted test" then it's something else.

If anything else arises (like launching glitches or UI glitches) I'll make sure to keep you posted. Otherwise, see you in two days!

And thanks for the reply/advice.

OK. Just tried to begin the test and I ran into some problems.


1: The lines are thicker than ideal. Lines this big make it really rather difficult to get all the details of the car right. Especially when they're blocked out entirely. This perfectly brings me to a question. Is there a way to change the thickness right now? Have I missed it? Or is it not implemented yet? Oh and the red circle is highlighting where the line thickness settings would normally be but isn't now.

2: Is this what vector lines look when they get huge? Or is this due to a different brush compared to the one I'm using? I typically set my line thickness to 4.00. So I wouldn't know what vector lines look when they get really huge. I do have some "add-ons" but I don't think the brush I'm using is a "aftermarket" one.

And if you'll note, there are three other menus at the top of the arc. Yes I clicked on them and I still didn't find a line thickness setting in them. Of course I could've just totally missed it but as far as I'm aware such a setting didn't seem to appear.

For comparison sake, here is what the same car looks like when I did it in my version of Krita (which isn't the pre-alpha version).


Sorry for not including the base I used in this picture. However I think the difference in line thickness (and detail in the image) is pretty obvious even with the technicality. And as you can see the line thickness settings are there in "Krita Prime" if you will.

Haven't tried seeing if the save function is working yet. Although there is an autosave file of the first image. However I think getting more results is going to be key here. As Adam Savage once said: "It's not Science unless it's repeatable"

The second tab has the line-thickness settings, but you might need to switch the line to 'no stroke'(first button) and back to 'flat stroke'(second button) for the settings to appear. This appears to be a bug.

Right you are sir. I went to get the line thickness setting in and found out that switching between "no fill" and "solid color fill" will bring the line thickness setting back into the open.

So this is definitely a bug. However with that cleared up, I can now get back to my plan. Thanks!

(Once again I apologize for the double post). I also apologize for getting this out later than expected. Life kinda got in the way so I couldn't really spend a full day doing the renders (however I was able to yesterday). So, here are some things to note before I show off what happened.

1: Krita 4.0 Pre-Alpha didn't crash at all during my testing.
2: I like the UI, except for that bug with the line thickness. Although it's just a bug and will probably be fixed later on.
3: I don't really notice any differences with the new layer system (however I didn't look that hard for the differences either haha).

With that out of the way. Lets get right into the results!

Section 1: Untainted images!

For this I'll only be showing 5 out of the 10 cars I did (so as to not clutter the post too much). If any of you want to see the rest of the cars then just ask and I'll post them. (This is also in no particular order).

We start off with the VLF Force 1 V10.

After making the car, I closed the file and reopened it in Krita and this is what it looked like after that. Exactly the same as in the image below.


Dodge Neon (the 2017 one for the Mexican market based off the Fiat Tipo).

After reopening the file.

What the car looks like (exactly the same as the image above).

PF generation Dodge Dart (RIP 2013-2016).

After reopening the file.

What the car looks like (once again exactly the same as the image above).

Dodge Challenger H-Cat Widebody.

After reopening the file.

What the car looks like (still the same as the image above).

Alfa Romeo Giulia Quadrifoglio

After reopening the file.

What the car looks like (another car that looks exactly the same as in the image above). I have more than these cars currently displayed but I think only 5 were needed to make my point. And for those wondering I didn't make the full car(s) for two reasons. One of them being it would've taken me way to long just to do 3 cars that way. The second reason being I wouldn't need the entire car to tell if something was off, so I only rendering what was necessary for me to play "spot the difference" if something occurred.

Section 2: Tainted Images!
DIsclaimer! I tried the method I spoke about previously and nothing happened (spoilers). So the next 5 cars would've have troubles had something happened (which nothing did). Now lets move on to the first car.

Dodge Copperhead concept.

This is what the car looks like after reopening the file.

And this is what it should look like (exactly the same as the image above).

Lancia Delta S4

What it looks like after reopening it.

How it should look (which is exactly the same as the image above once again).

Dual-Ghia L6.4

What it looks like after reopening the file.

How it currently looks (same as the image above).

Cunningham C3.

What it looks like after reopening it.

How it looks right now (same as the image above).

Chrysler 200C Concept.

How it looks after reopening it.

What it looks like (same as the image above).

There you have it. Thanks to the Scottpetrovic for suggesting I test out the latest Krita version and thanks to TheraHedwig for helping me fix the line thickness problem. Any suggestions or thoughts on the subject are still welcome.
