1944465 - MediaPD~oder segfault in libLLVM-17.so.1

Status: UNCONFIRMED

(Core :: Audio/Video: Playback, defect)

Description

[denalimoose]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:134.0) Gecko/20100101 Firefox/134.0

Steps to reproduce:

This has been happening for several months. While watching Twitch.tv, sometimes (not every time) when an AD starts to play, all video will stop playing and the Twitch site gives me a button to 'Reload the player'. Reloading the player brings the stream or AD back to normal. Until it tries switching again, might not work.

I have 2 monitors, Twitch is playing on one monitor and I'm on websites on the other monitor. Some webpages, that do not appear to have video playing, seem to trigger the same kind of 'crash' in Twitch.

Also, this amdgpu driver is the AMD Radeon for Linux driver, not the opensource version. I needed it for openCL support. https://amdgpu-install.readthedocs.io/en/latest/index.html is where I got it from.

Actual results:

In dmesg I see messages like this at the same time.

Attachment: dmesg_libllvm-17.txt

Not sure if the dmesg output was properly visible. I get dozens of these messages per day.
Currently I have no way to solve this. Just keep clicking the "Reload" option.

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