Public bug reported: I've reported this to NVidia, but I don't think it is just an NVidia issue.
Using Ubuntu's 24.04.2 LTS official 550 drivers, under X11, performance (FPS - frames per second) of my player is 60 FPS at 4K. Under Wayland, performance suffers a drop to 48 FPS at 4K. OpenGL performance is a solid 60 FPS at 4K on both X11 and Wayland. With the latest NVidia drivers on its PPA (570), under X11 and under Wayland, FPS drops to below 30 FPS. Tests are done with my own Vulkan video player, which you can download from: https://sourceforge.net/projects/mrv2/files/vulkan/ You can test playback performance with these free movie files: https://mega.nz/file/qX5HSIAS#Jy1lCoruENeMDjR2bIdbNcETzVZ0aNvEdEUVIgOVu-c https://mega.nz/file/uGJDXK7Y#tCDFYyZKtQUx3rggD9z0DGWmbuNV81IBLSk9wGxu0bg In my player, you can see the FPS with CTRL + H -> FPS.
