Bug ID: 391486
Summary: Nvidia 340x drivers - KWin Compositor won't use OpenGL
backend
Product: kwin
Version: 5.12.3
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org
Reporter: dan.f.k...@gmail.com
Target Milestone: ---
OpenGL 2.0 and OpenGL 3.1 stopped working as the compositor backend after an
update. XRender does work.
When attempting to set the compositor backend in System Settings | Hardware |
Display and Monitor | Compositor, it appears to set correctly (i.e: no errors
are prompted), however
----
[user@host ~]$ qdbus org.kde.KWin /KWin supportInformation | grep -i compos
Composite: yes; Version: 0x4
compositingMode: 1
useCompositing: true
compositingInitialized: true
windowsBlockCompositing: true
Compositing
Compositing is active
Compositing Type: XRender
----
I'm not able to enable certain desktop effects such as Magic Lamp, Wobbly
Windows, etc, so it's obvious XRender is actually in use.
