I downloaded the 4.4.2. update that’s on the first page of the site, and have a (frankly, irritating) bug that the colour on the canvas is inverted from what the layer thumbnails, colour palette, and final downloaded piece is, without any sort of filters or blending modes being applied. Here is a screenshot:
Hello and welcome to the forum 
Is the first image a full screenshot when using your previous version of krita?
Is the second image a section of the canvas after you’d installed version 4.4.2 on the same computer?
Have you made any changes to the settings at all?
Can you try swapping between OpenGL and Angle (restart needed) in Settings -> Configure Krita -> Display group -> Canvas Accleration tab?
Can you try disabling Canvas Graphics Acceleration on that same tab and then restartng?
Can you post the contents of Help -> Show system information for bug reports?
Thank you for replying! I just downloaded this version two days ago, and have uninstalled it and reinstalled it a few times to try and fix the problem, but it didn’t works. So the only version I have is 4.4.2., and I have only the default settings.
The second picture is after I exported my picture, which had inverted all the colours that were on the canvas (but were the same for all the layer thumbnails.)
I’m going to try all your suggestions now, thank you!
Swapping to OpenGL fixed it!! Thank you so much, you’ve saved me so many headaches and frustration!! <3
I’m glad it’s fixed and wrking for you.
I didn’t realise that the inversion happened in an exported .png image.
@tiar may know why that could happen and be fixed by switching from Angle to OpenGL. It’s a mystery to me.
The color inversion is always a problem of the graphics drivers. Broken drivers swap the blue and red channels in RGB ot BGR – without any way for Krita to figure out that that’s the case.
I’m puzzled because this has been seen before but with the canvas image having the R-B inversion.
Here, the canvas image is ok and it’s the png exported image that has the R-B inversion.
Interestingly, the colors on the Layers docker were also swapped. @MystifiedMina are you sure the color selector (not color sampler, but color selector, the big rectangle with colors) worked for you? As in, showed the same colors you were painting with?
No, It said I would be using one colour, but then the colour on the canvas would be wrong. I realize now that the colours weren’t inverted, but the red and blues were changed, it was really odd, but thankfully it was fixed by swapping to OpenGL in the Canvas Acceleration tab.
I wasn’t also aware that it could be a problem with my computer, not a bug in Krita.
Yeah, then it’s normal for this kind of problem.
Can you please tell me what graphics card you have?
I’m not sure, It’s a family computer that a couple years old (not ancient, but not exactly new, it works well for school and drawing though, which is all that matters for me)
When I looked in my task manager(just now) it didn’t have a thing for a GPU in the performance tab, but the CPU is a Intel®Core™2 Duo.
If this really doesn’t have a graphics card that would explain a lot…
It’s probably Intel’s integrated graphics which is fine for most home/office work.
If you do Help -> Show system information for bug reports, that will show what krita can see inside your computer, including graphics capability.
tq so much it helped me
