Bug ID: 468895
Summary: Desktop freezes when Night Color feature kicks in
running Wayland with NVIDIA proprietary drivers.
Classification: Plasma
Product: kwin
Version: 5.27.4
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: dcalv...@gmail.com
Target Milestone: ---
SUMMARY
***
With the Night Color feature enabled, running Wayland with NVIDIA proprietary
drivers, one or more monitors freezes momentarily. If left unattended the whole
kwin session freezes on all monitors.
On the logs, the message : "kwin_wayland_drm: Failed to create gamma blob!
Invalid argument" can be seen at each time the desktop freezes.
After a few seconds it will unfreeze and let you continue for maybe a minute
more before going at it again, I'm guessing it is the Night Color feature
attempting to start again.
***
STEPS TO REPRODUCE
1. Be running a Kwin Wayland session using Nvidia proprietary drivers.
2. Have the Night Color feature enabled.
3. At the time the Night Color feature is supposed to kick in, the issue is
observed.
OBSERVED RESULT
One or more monitors freezes momentarily. If left unattended the whole kwin
session freezes on all monitors.
EXPECTED RESULT
Night Color works as expected.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 5.27.4
KDE Frameworks Version: 5.105.0
Qt Version: 5.15.9
Kernel Version: 6.2.12-zen1-1-zen (64-bit)
Graphics Platform: Wayland

Memory: 15.6 GiB of RAM
Graphics Processor: NVIDIA GeForce GTX 1070/PCIe/SSE2

ADDITIONAL INFORMATION
3 monitors: One Display Port, one HDMI and one DVI.
It seems to favor freezing the DVI monitor first, but the rest will follow
soon.
To avoid this issue and continue to have a working system through the night
hours, the workaround has been to disable Night Color completely.
Seems related to #450327.
