Title:
Poor desktop frame rate in Nvidia Wayland sessions
Status in Mutter:
New
Status in mutter package in Ubuntu:
In Progress
Bug description:
On a desktop with a single Nvidia GPU and single monitor, desktop
performance is poor in Wayland sessions.
The main culprit seems to be that all rendering gets deferred until
meta_drm_buffer_gbm_new_lock_front by the Nvidia driver, which blocks
the main loop at a time we are not optimised to handle blocking.
