Expected results:

Nothing

Just want to note that I couldn't find a reliable way to reproduce this. It happened multiple times this week but seemingly at random times with different sites/activities.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Please uninstall deprecated libva-vdpau-driver: It doesn't support vaGetDisplayDRM and crashes.

It might be this one: https://salsa.debian.org/multimedia-team/attic/vdpau-video/-/blob/63450ffea86143d418c6e83cb8d2828d3a7beb25/src/vdpau_driver.c#L188

const char * const x11_dpy_name = XDisplayString(driver_data->x11_dpy);

vaGetDisplayDRM() doesn't fill ->x11_dpy

VAAPI should be blocked for vdpau_drv_video.so.
vdpau_drv_video.so is deprecated and has been removed from Debian.
Debian Buster (oldstable) was the last release that had a package for it: https://packages.debian.org/oldstable/vdpau-va-driver
