System: Arch Linux
Kernel: Git (72cf0b07418a9c8349aa9137194b1ccba6e54a9d)
MESA version (19.2-4689e98f)

When using Firefox Webrender and browsing some heavy site the system freezes
but mouse cursor is still able to move as normal.

This wasnt an issue on my last build of MESA (db329260bff) and once i build new
version the system started to freeze.

As a temporary workaround im using my last build thats working but this is not
an OK solution for obvious reasons.

I found bug 108718 which is the same as this one but nobody responded to it and
i think it got solved as the reporter didnt respond to it anymore thus i think
this is an regression.

Im unable to provide dmesg of the issue as when the system locks up i cannot
even go to TTY.
Will try to set up SSH and capture dmesg like that.
