Bug ID: 502651
Summary: The background of translucent widgets is brighter than
SDR white in HDR mode
Classification: Plasma
Product: plasmashell
Version: 6.3.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
Transparency (and fade-in) effects applied to plasma widgets will make them
show brighter than configured SDR brightness on HDR display. This is undesired
for UI elements, especially when the content (like application icons) is still
composited with SDR brightness.
STEPS TO REPRODUCE
1. Enable HDR in Display Configuration
2. Open a window with SDR white for reference
3. Compare brightness of translucent widgets and SDR white
OBSERVED RESULT
The background of translucent widgets is brighter than SDR white
EXPECTED RESULT
The background of translucent widgets is not brighter than SDR white, just like
how it works on SDR display.
There is no easy way to capture HDR output from kwin at the moment, therefore
no screenshot available.

brightness.
