[kwin] [Bug 500172] Setting a colour profile with Wayland seems broken on TeraScale-based GPUs
https://bugs.kde.org/show_bug.cgi?id=500172 Wedge009 changed: What|Removed |Added Status|REPORTED|RESOLVED Resolution|--- |FIXED --- Comment #12 from Wedge009 --- I just updated to Kubuntu 25.04 with Plasma 6.3.4 and Plasma colour correction seems to be working fine on Wayland even with TeraScale-based GPUs, so I don't see any need to keep this open. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=500172 --- Comment #11 from Wedge009 --- I just tested KDE Neon live session (neon-user-20250320-1319.iso) with Plasma 6.3.3 and setting an ICC profile seems to function on TeraScale GPU (ie it does the job of colour correction). It seems to be okay regardless of whether I set prefer efficiency or colour accuracy. So it seems resolved for Plasma 6.3? -- You are receiving this mail because: You are watching all bug changes.

I still intend to retest KDE Neon (for Plasma 6.3). I just noticed the User Edition has been updated, I'll test it when I get back home tomorrow. -- You are receiving this mail because: You are watching all bug changes.

Please test Plasma 6.3 anyways though: In addition to more aggressively using hardware acceleration, we also changed some things for how the shadow buffer works - as long as you leave the color accuracy as "prefer efficiency", it'll try to use only 10 bits per color buffers rather than 16, which should be much better tested on the driver side. -- You are receiving this mail because: You are watching all bug changes.

I don't have any NV GPUs to check since the last one died a long while ago. I also don't use Intel GPUs. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=500172 --- Comment #5 from Wedge009 --- Thanks for the response. I contrast this with the GCN system that has colour profile working and there are entries under Properties for the CRTCs - including 'GAMMA_LUT' and 'GAMMA_LUT_SIZE'. So maybe the radeon driver (contrast amdgpu) doesn't have what you were suggesting regarding gamma LUTs? -- You are receiving this mail because: You are watching all bug changes.

If the driver exposes a gamma lut, Plasma 6.3 might work around the problem. The actual issue is most likely that the driver support for 16 bit floating point buffer formats isn't well tested - we've hit several driver bugs with them on newer cards. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=500172 Bug Janitor Service changed: What|Removed |Added Status|REPORTED|RESOLVED Resolution|--- |DOWNSTREAM --- Comment #1 from Bug Janitor Service --- Thank you for the bug report! However Plasma 6.1.5 is no longer eligible for support or maintenance from KDE; supported versions are 5.27. (LTS), and 6.2 (non-LTS) or newer. Please upgrade to a supported version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. If you need support for Plasma 6.1.5, please contact your distribution, who bears the responsibility of providing support for older releases that are no longer supported by KDE. If you can reproduce the issue after upgrading to a supported version, feel free to re-open this bug report. -- You are receiving this mail because: You are watching all bug changes.
