(GNOME 42, NVIDIA, glxgear, pymol) Status in gnome-shell package in Ubuntu: Incomplete Bug description: OS/software: Ubuntu Jammy Jellyfish (development branch), GNOME 42.beta, X11, NVIDIA-driver-510 (510.54) Hardware: Intel® Xeon(R) CPU E5-1650 v2 @ 3.50GHz × 12, 31,3 GiB RAM, NVIDIA Corporation GP106 [GeForce GTX 1060 6GB] How to reproduce: open glxgear, on the same workspace, move any window, there is badly dragging lag. But there is no lag if move window on a different workspace. CPU/GPU usages are normal (<3%). Disable Sync to VBlank in NVIDIA Settings can solve this issue, but CPU/GPU usages are abornmally high (single core CPU>80%, GPU>10% only for glxgear). Both NVIDIA-driver-510 and NVIDIA-driver-470 have the same issue. But another Intel-GPU based laptop works fine. This is not a glxgear bug, as other realtime 3D rendering (PyMOL, Blender...) casue the same issue. Possible reasons I guess: NVIDIA driver bug, kernel bug, or GNOME 42 bug.
