Bug ID: 460512
Summary: Using specific color in 32-bit float image depth can
cause crash
Classification: Applications
Product: krita
Version: 5.1.1
Platform: Compiled Sources
OS: Microsoft Windows
Status: REPORTED
Severity: crash
Priority: NOR
Component: Color models

Target Milestone: ---
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
