Description Peter Eszlari 2025-08-07 20:13:51 UTC 
When running inside QEMU with VirGL, "System Details" in GNOME 48 shows for my GPU:

"virgl (Intel(R) UHD Graphics 620 (KBL GT2))"

In Plasma 6.4.3 I only get:

"llvmpipe"
Comment 1 Peter Eszlari 2025-08-07 20:19:26 UTC 
To add mor info:

Output of 

$ glxinfo | grep "renderer string"

is the same for both the Plasma and GNOME session:

"OpenGL renderer string: virgl (Mesa Intel(R) UHD Graphics 620 (KBL GT2))"

That bug is specific to the proprietary NVIDIA driver. I tested git-master, this bug here is not fixed.
