Bug ID: 509617
Summary: Add to "Window Rules" HDR property.
Classification: I don't know
Product: kde
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-bugs at kde.org
Reporter: adolfotregosa at gmail.com
Target Milestone: ---
SUMMARY:
HDR has been a controversial topic:
https://bugs.kde.org/show_bug.cgi?id=499934
https://discuss.kde.org/t/hdr-calibration-tool-6-4/34592
Since there’s no “solution” to a “not a problem,” I’m requesting a way to turn
HDR on and off for applications, and Window Rules seems to be the most obvious
place to implement this.
HDR ON when the application is running, OFF when it stops. This seems like a
reasonable request, similar to how we have the Adaptive Sync property. While
not perfect by any stretch, I don’t see any other practical solution.
This way, the 100% Brightness Slider can be set to what seems to be the
passthrough value of 203, so it does not affect HDR content in any way, shape,
or form.
While I am genuinely trying to understand the reasoning behind HDR handling as
it currently stands, it does not help users like myself who want HDR content to
be presented on the display unaltered, while also avoiding excessive brightness
in other situations.
Thank you.
