Bug ID: 498328
Summary: HDR not working for dx12/vk3d titles (Gamescope)
Classification: Plasma
Product: kwin
Version: 6.2.5
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: platform-drm
Assignee: kwin-bugs-n...@kde.org
Reporter: syed.talha.kha...@gmail.com
Target Milestone: ---
I am trying hdr on kde, I am able to run DXVK titles and MPV (wit the vk
layer), and those work perfect. I just have HDR400, My monitor isn't that great
when it comes to hdr, but still look better never the less.
But when i try to run dx12 titles in gamescope, I just get black screen, but
the game is running. Audio everything is working but no display.
I get these error, when I try to run dx12 title with hdr, DXVK and MPV works
fine.
