User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:107.0) Gecko/20100101 Firefox/107.0
Steps to reproduce:
I watched a video in one window and highlighting text in a second. Sometimes all windows will freeze and Firefox becomes unresponsive. It does not always happen, but very regularly. I narrowed it down to where it would only crash when I watch a video while using hardware acceleration.
Actual results:
All Firefox windows freeze, become unresponsive and I have to force kill them. When disabling hw accel it won't freeze.
I recorded a short video for demonstration. I'm able to reproduce it in about 30 seconds each try. (I'm highlighting text like a mad man to "brute force" the freeze, but it also randomly freezes when selecting text like a normal human.)

(freeze happens at 26s)
Expected results:
Not freezing

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.

Thanks, it looks like an x11 issue for sure. Also, there is another bugzilla issue I didn't found https://bugzilla.mozilla.org/show_bug.cgi?id=1800903
