If you enable the "dma-buf-screen-sharing" experimental feature, any program trying to screenshare (including the GNOME Shell screen recorder) crashes upon attempting to record the screen.
For example, xdg-screen-cast, produces the following error:
fish: Job 1, 'Desktop/xdp-screen-cast.py' terminated by signal SIGBUS (Misaligned address error)Here's the core dump and the executable in case it's helpful:
core.xdp-screen-cast.1000.5bcbd6dc57db43f0987c5821a79a479f.3528.1617456016000000.zst python3
