I work simply (traditionally/few layers/no filters or extras). Not great at taking in anything from complex/technical information. If I may ask for your help with something, I'd be very grateful.

Despite all the excellent features and brushes, the issue of painting ghosting onto the layer beneath is stopping me being able to use Krita. The only reference I can find to this, in a reddit thread, is advice to duplicate the painting a number of times ... I'm not able to adapt my very transparent/blended style like that.

I can't erase above the imprinted ghost, without having to edit the layer beneath, as can be seen in the image below (the white around the plant doodle is the underneath layer) ... and it adds more work and blocks the process up, as I have to edit/fix the ghost every time changes are made. The only way no ghosting happens is if I choose and fill the background before painting anything above, and that unfortunately again blocks the natural process of altering the background at various stages during painting.

I've not experienced this before in a digital painting program (ipad and Windows, before to Linux), and am wondering what I'm missing that fixes this. I can't move from Linux, and MyPaint's lack of internal editing is an issue, so please can I ask for your assistance. (I had been using the ipad, but too worried about decline showing in eyesight.)

Thank you.

What kind of brushes do you use?

The ghosting should only happen if you're trying to paint with white onto the top layer instead of using the eraser mode.

Thanks for response. I'm using some inbuilt and a few different ones that various brushmakers made for Krita 4. I use the hard eraser brush on the layer above. I don't paint with white first/directly. The ghosting happens with any colour or brush, and can be either white or a kind of 'negative' of the colours I've used ... I think that 'negative' occurred when I used a brush with colour dodge on the top layer, on top of the painting that was already there (not directly onto the transparency).

I've just done this, hopefully clearer [ipad photo makes the cream look white]:



with this brush, from the Krita 4 set:



At first I'd filled the underneath layer with brown, and painted the scribble. Then I changed it to blue, and immediately the ghost shows.

If I use the hard eraser on the top painted layer:

Here's your problem

Color dodge will mix with transparent as if you're painting normally. To avoid this, alpha lock your layer(the checkerbox icon) when using color dodge and the like, another option is to try and use a brush using the filter brush engine, which only affect non-transparent pixels.

Edit: BTW, Your computer can make screenshots for you, should be easier to deal with. Mac OS, Windows.

I rarely use colour dodge. This ghosting happens with every brush, without any effects/filters, as I've shown with the illustration above, using a basic Krita 4 brush without any effects/dodge. There must be some issue with Krita, if using it in it's most basic form is resulting in this issue. I can't do technical/filters etc.

The picture shows the pop up that says the name of the brush ... the only way to take a screenshot of that was with the ipad, as the pop up disappears when trying to use pc screenshot software, when using linux (flameshot) anyway.

I'm sorry, can you share a kra file then? Because I cannot figure out what is going on for you.

Another option is to try and use something like peek to record a small gif or mp4 of the recording and share that.

Will get on with that. Not sure how to upload a video (I'm not on youtube) but will look into peek.

Not sure how to upload these ... postimage won't accept the gif (3.5mb). I've never uploaded to Mega before ... tried, won't work.

Can I drop the kra into the IRC?

Thank you! I now now your issue: The fill tool by default takes into account other layers when filling. This makes it easier to fill in a line drawing that is on a seperate layer. If you wish to fill a layer completely, either toggle limit to current layer in the tool options, or, even more easy, go to Edit -> Fill with Foreground color(the hotkey for this is 'Shift+backspace')

Hopefully this resolves you issue

It's fixed! Tool Options easiest. Makes a big difference to find this solution.
