Bug ID: 427206
Summary: HDR canvas color changes when changing the brightness
in the system
Product: krita
Version: 4.3.0
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: HDR
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Because of bug 412881 it is nearly impossible (and I don't use this word
lightly) to work with Krita's HDR on Yoga c940 without making the brightness of
the screen higher. But then the HDR canvas gets brighter as well, showing
incorrect colors and artifacts.
STEPS TO REPRODUCE
1. Make sure your system is capable of displaying HDR.
2. Open Krita using the lowest brightness of the screen. The interface is dark,
but the canvas shows correct colors.
3. Change the brightness of the screen to be higher.
OBSERVED RESULT
The HDR canvas is getting brighter, shows incorrect colors and artifacts.
EXPECTED RESULT
The HDR canvas looks the same as before.
ADDITIONAL INFORMATION
I believe system tells applications like Krita incorrect HDR max value. Maybe
there is a way to overwrite this, let the user set the value on their own? It
could show the value system tells it, so the user could just check what value
it says when the brightness is lowest, and then copy it to the overwriting
field so Krita will always use that value instead of whatever system tells it
to.
