Description Kampidh 2022-10-15 23:12:08 UTC

SUMMARY
While working with 32-bit float image, a crash occurred when painting with specific colors (Red at 1.0 value, including white with [1.0, 1.0, 1.0] value). Something that I observed is that in float, canvas white and white from advanced color selector only shows at [0.999..., 1.0, 0.999...], using a specific color selector to bring it back to all 1.0 and painted it cause the crash as well. However, the crash didn't occur at 16-bit float.

At first, I thought it was because I used Rec.2020 Profile, but when I tried with sRGB and ACES, it also crashes. So does on different TRCs (Linear, sRGB)

A workaround is to disable 'Allow Little CMS optimizations' on Color Management setting. From the crash logs, looks like the crashes has something to do with lcms fast float module?

Another workaround that I discovered is using OCIO. However, if there are pixels with those specific colors are on canvas, disabling OCIO will directly result in crash as well.


STEPS TO REPRODUCE
1.  Create new canvas with 32-bit float depth
2.  Try to paint with pure white [1.0, 1.0, 1.0] from specific color selector
3. 

OBSERVED RESULT
Krita crashes

EXPECTED RESULT
Should be able to display the color properly

Comment 1 amyspark 2022-10-15 23:53:24 UTC

I'll try and reproduce, in the meanwhile, can you send a file that will reproduce the crash if the Fast Float plugin is enabled?

Based on your observations, this should be achieved by painting normally with the maxed out value, saving, then enabling the optimizations.

Float32 Test File

200 x 200px image, Rec.2020 Linear Profile, 32-bit float. Color patches painted in RGB [1, 0, 0], [0, 1, 0], [0, 0, 1], and [1, 1, 1] selected from Specific Color Selector.

Crash to open with LCMS optimization turned on.

Oh right, I forgot to add that values above 1.0 didn't cause crash (for example to paint with [2.0, 2.0, 2.0] white)

ICC Profile from DisplayCAL calibration

Update:
So apparently this only affects the screen that have a custom profile on it. My drawing tablet is calibrated using displaycal(argyllcms) and have XYZLUT+Matrix profile on it (that I also set on Krita's Color Management > Display). When opening on secondary monitor without custom profile (sRGB default) it didn't crash.

Tried with another system with Krita 5.2.0 prealpha also confirmed this behaviour, no crash with sRGB and crash with calibrated profile.

Here I attached the custom profile that my drawing tablet has to further replicate the crash.

Comment 5 Kampidh 2022-10-17 09:48:53 UTC

And after extensive testing with other profile types in DisplayCAL, here's what I got:

- XYZ LUT + Matrix without BPC (default) = crash
- XYZ LUT + Matrix with BPC = crash
- L*a*b* LUT without BPC = crash
- L*a*b* LUT with BPC = crash
- Curves + Matrix without BPC = crash
- Curves + Matrix with BPC = not crash

Additional info:
From my observation, only curves + matrix with BPC that show a significant difference (lift) in darker tones (my tablet display indeed have bad blacks though), while in LUT-based profiles, BPC doesn't seem to do anything. But this may be for another scope, as it might related to displaycal/argyllcms instead.

Comment 6 amyspark 2022-10-19 00:19:18 UTC

Confirming bug, reproduced on first try with commit b19356bae8 and LittleCMS 2.13.1 *and* 2.14rc1.
