Bug ID: 453114
Summary: Enabling EGL for Kwin Disables Desktop Effects for
Nvidia Proprietary Drivers
Product: kwin
Version: 5.24.4
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: needs_verification
Severity: normal
Priority: NOR
Component: egl
Assignee: kwin-bugs-n...@kde.org
Reporter: nekone...@protonmail.ch
Target Milestone: ---
Flags: Wayland?, X11+, NVIDIA+
SUMMARY
Curious that the Nvidia proprietary driver might like using EGL (I've heard
before that Nvidia leans that way), I attempted to switch over to it with Kwin
by setting "KWIN_OPENGL_INTERFACE=egl"; however, after doing so and rebooting,
I found that transparency effects, blur, and other "appearance" category
desktop effects ceased to function.
This also broke the "screen edge" task switching feature as well.
STEPS TO REPRODUCE
1. With an Nvidia card, install the 510.60.02 driver
2. Set the "KWIN_OPENGL_INTERFACE=egl" environment variable for the next
session (can do this by dropping a script for it in profile.d)
3. Reboot
4. Login to a Plasma X11 session
OBSERVED RESULT
Expected desktop effects, though still enabled, are non-functioning with EGL
set.
EXPECTED RESULT
Enabled desktop effects should still function with Kwin set to EGL.
