Lately I’ve had some problems with the graphics, that manifests after the computer has been on for a while. This includes KDE settings freezing and taking up all CPU when viewing the screen settings, lock screen being broken, and openGL programs not rendering, though they start rendering if you switch to another session. Might have something to do with the recent update to the Nvidia-driver, I’m gonna try restoring a snapshot and see if that helps.
I’m on a Nvidia Geforce GTX 780, with the proprietary driver.
[INDENT=2]1.5 Nouveau 3D/DRI Driver May Crash KDE Applications
With openSUSE Leap 42.2, the Nouveau Mesa/DRI driver for 2D/3D rendering is considered experimental. The Nouveau kernel/KMS driver and the Nouveau X.org/DDX driver for 2D rendering are still considered stable.
When the Nouveau Mesa/DRI driver is in use, some applications may crash, especially KDE and Qt applications. The driver is now in a separate package called Mesa-dri-nouveau, which can be removed in case of problems.
Without this driver installed, there is no hardware 3D acceleration support on any Nvidia GPU and no 2D acceleration on newer Nvidia GPUs that use Glamor for fast 2D operations. Kernel Mode Setting and basic 2D are still available, as is 2D acceleration via EXA on GPUs from the Nvidia GPU generation code-named Kepler (introduced in 2012) and earlier. 3D operations are supported via software rendering.

As well as deleting it, you’ll need to drive a stake through its heart
by taboo-ing it else it will rise from the grave.

I did mention I was using the proprietary driver, so I don’t think Nouveau stuff would apply. If you’re wondering about the version it’s 375.20. I’ve now rolled back to 367.57, which seems to work fine.
