Description Jens Reuterberg 2020-11-09 08:54:36 UTC

SUMMARY
Opening the Systemsettings shows either the main view and a black sidebar (which can't be clicked) or if you open a specific KCM, the sidebars and the main kcm is blacked out.

STEPS TO REPRODUCE
1. Open System Settings from Krunner, Konsole or Kickoff
2. -


OBSERVED RESULT
Sidebar Blacked out if you launch systemsettings, active KCM blacked out if you launch that KCM specifically.

EXPECTED RESULT
That they are visible.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Opensuse Tumbleweed 20201106
(available in About System)
KDE Plasma Version: 5.20.2
KDE Frameworks Version: 5.75.0
Qt Version: 5.15.1

ADDITIONAL INFORMATION
Nvidia Driver 450.80.02
Kernel: 5.9.1-1-default

This is after installing the proprietary Nvidia drivers and I vaguely expect that to be the issue hence including Kernel and Nvidia Driver version.

When launched from Konsole this is the output:

Supposedly fixed in the latest version of the Nvidia driver.

Thank you! Sry I dug like crazy to make sure it wasn't a duplicate - my bugzilla game isn't all there
