Hi,

SEE IMAGE please.. It's hard to explain.

How do you disable OpenGL on Krita 4.0?
When in Preferences > Display, ticking canvas acceleration does not unlock the OpenGL option (it is stuck on) and it remains grayed out. Disabling openGL in 3.3.3 fixed a bunch of issues I was having and I suspect a cursor bug I'm seeing in 4.0 is due to OpenGL being on by default.

The issue is that the cursor is stuck looking like <-|-> which is the cursor shown when resizing a part of the interface. Whenever the cursor passes over part of the interface that can be resized, it changes momentarily to this resizing icon but then does not change back to the expected drawing/brush cursor when over the canvas.

The issue is only present in 4.0. We tried reinstalling 4.0 twice. We tried restarting the system and software numerous times. We reset the Wacom Intuos tablet config. Nothing is preventing the cursor from sticking to this resizing icon.

I am having the exact same issues on High Sierra. I even thought of buying a new Wacom Intuos but apparently it is not drive related. Krita is the only software I have that has that strange issue.

Oddly enough, if I lift the pen from the tablet, the painting cursor comes back, but doing it constantly ruins the whole workflow.

The second issue I'm having has to do with the brush tags. I cannot assign favourite brushes, because they disappear/don't show. The only time I managed to have some success, the next time I opened Krita everything was gone again...


Thanks for the attention! Appart from those issues, Krita 4 is a fantastic update!

I've finally managed to setup my cintiq hybrid companion with my macbook pro. That was a very convoluted process, and it took up all of my afternoon. I'll try to do some testing after dinner, but a short preliminary test didn't show any problems for me. I suspect it's related to https://bugs.kde.org/show_bug.cgi?id=390642 though.

Thanks so much for looking into this. We all really appreciate that the software is free and it really is a fantastic program.

I have not been able to reproduce this using only the Mac trackpad -- I'm not sure if that's helpful but I thought it would be worth mentioning that it seems to be isolated to conditions where a tablet is the active input device. I'll update this page if I find out more.

Again, thanks for your time and efforts!

Cheers

edit: I did some googling and I think this is a Wacom driver/hardware issue. Search "wacom tablet double cursor". I might be wrong but it seems like Wacom drivers are the cause of a lot of problems similar to this.

How did you manage to setup your cintiq ? I have the same annoying problem on Mac OSX El Capitan with an intuos 3 tablet. The tablet cursor (there is no problem using the mouse) disappears often when hovering over the UI, or when using a pop up menu (left clic for tools)... If moving the mouse, the cursor comes back, but it often stays stuck displaying the wrong tool...
So if there is a way to fix this, I would love to know.
I also suspect it's a wacom issue more that a Krita problem... I removed my Intuos 3 driver and tablet and tried with a more recent Intuos Pro and its drivers, but I have the same issue. I might try to make a new clean install of a new OS up to date with OS X 10.13 later to see if that's better, but I have no clue how to fix this and it's very annoying, making Krita almost unusable...

I have the same problems described here (Sierra 10.12.6, Wacom). Besides, when I start using vector tools, the program goes crazy: it starts working quite slower, I cannot choose a different tool at once. I came back to 3.3.3 and it works well again. My Wacom is fairly ancient and I doubt if I can upgrade somehow its drivers.

I am running Krita 4.0.1 on an iMac (late 2015) with High Sierra with an Intuos 5 Wacom tablet. I have had no problems. It's funny. When I was trying to use Krita 3.3.3, it would not work for me, as if the Open GL was not turned on. Now everything works wonderfully. Everything is updated to the latest drivers etc.

Sounds like you might've got a mac with a discrete AMD gpu; those setups were buggy to the point where for some reason one couldn't save to png or jpg. We worked around that in 4.0.

If relating to me, I don't know. But Krita was the only program that acted that way. So, on the other hand, yes, something different was done in 4.0.1 that made everything work just fine.......so far.

I've made a clean install of OSX High Sierra but the problem remains with Krita 4. I have to put the pen away from the tablet everytime I hover the UI to the color palet for exemple, or the cursor is buggy and stays with the wrong icon, or the tablet doesn't work at all...

But if I use Krita 3.3.3 it works fine ! And with the same tablet (intuos 3) it works perfectly fine with Krita 4 on my linux workstation...

So it really looks like a wacom issue, but it worked fine with Krita 3...
I tried to adjust the pressure settings, but I really don't see what else I can do to get rid of this bug with Krita 4...

And my Macbook pro works with an Intel Iris 1536 Mo not an AMD GPU apparently.

I reinstalled 4.1 and it works fine, without the tablet, which makes me upset. I will have to stick to 3.3.
Is there going to be done any changes? Or is it strictly due to the drivers and nothing can be amended?

"Is there going to be done any changes?"

I am not planning to work on this myself, so whether anything is going to be done depends on some macOS user stepping up to work on it. I've only got two hands and one brain, so unless mac users start helping out, Krita on macOS will stagnate. I've said this before, and I guess I'll have to say it a hundred times more, until mac users finally realize that!

For me, macOS is the third platform, the least important and interesting one, with the worst hardware and the worst user interface and the worst development experience. I hate having to work on macOS. That means that whenever I have to choose what to do, mac-specific bugs have the lowest priority for me.

I ported Krita to macOS and keep builds for macOS in the hope that mac will turn up and start helping out. Instead all I get is bug reports I cannot reproduce anyway.

Hey boudewijn,
I can totally understand your position. OSX suffers often from this in the open source community, and I totally get why.
I'm also not very happy with their hardware and other developments... Anyway, the linux build is perfect and as you mentionned, if there is no OSX users ready to get involve to fix thoses bugs, it will slow down the whole Krita development and that is not a very good idea.
So keep doing your amazing work !

But now I feel guilty for not having graduated in programming. I have zero knowledge of how to fix bugs, so I find it my duty to report them so that people involved in the development can do something with them as it is not only my problem. I wish I had a good PC to work at but I do not. So please, do not give up on us no matter how unpleasant it feels to work out an osx version. We appreciate it.

As for the bugs themselves, I tried to use 4.1 with Cintiq 16 and it does not work well either. I know some people on osx have no problems using 4.1 so what can be wrong?

I too have a Wacom Tablet (different from the ones already posted) and am having this strange issue.
I also share many of the words and feelings stated.

I am an artist and have none programming experience. As much as I wanted to solve this (and other OS X related stuff) I wouldn’t even know where to start.
When I first read that it was going to be a Mac version of it, I got really excited. I even start learning it with a very buggy release that gave me more headaches than anything else. But I kept believing in it and hoping that eventually all the bugs would eventually get caught.
I also start reporting the bugs I was encountering, because it was the only way I knew that could help the development team.

Again, I’m an artist not a programmer. I got drawn to Krita because of it’s artistic value and what it can do. And believe many people came to know Krita because they are also artists and want to do art.

Also, for me, and having tried many different OS’s over time, I find that OS X is much more user friendly and simple as an environment. Unfortunately, I don’t care too much about what’s happening under the hood as long as things work.

This long email to say that it must be very difficult to maintain this project with just two hands and a brain
But please, don’t abandon us. If we take our time to report bugs, write on forums, … is because we care!

Finally, what can we non programmers do more to help solving this strange behaviour?

Thanks for listening. And thanks for all the hard work and attention put in this fantastic software.
