Hello,
-
OpenMandriva Lx version: 25.02
-
Desktop environment (KDE, LXQT…): Plasma
-
Description of the issue (screenshots if relevant):
NVIDIA performance in Plasma Wayland is very hitchy, even in Plasma 6.3.2
Areas where blur is expected is just transparent (usually a sign that graphics isn’t running properly)
Can’t replicate the problem in KDE Neon or Kubuntu (both Wayland) & with the same GPU. KDE Neon setup has been the same setup since Plasma 5, and switched to Wayland during alpha/beta of Plasma 6 on Neon experimental.
- Relevant informations (hardware involved, software version, logs or output…):

Continuation of this post:
Hope this log helps. I haven’t had the time to play around with this VM, so the original post closed.
I tried the fallback X session, but it just loads a terminal window of sorts with white background.
I’ll try to generate the part where desktop crashes to SDDM, but I haven’t had luck. Whenever it crashes, I forget to generate it.
