Dual monitor screen corrupt on wakeup [RX5700, 5.7]
Hello,
I have 2 identical monitors each connected over display port to a RX5700. I run Debian sid. Here is what happened earlier, it's the first time I see this issue:
- Both monitors A and B went to sleep per usual power saving behavior
- I wake up the computer, only monitor A wakes up, B does not
- Monitor A displays on its right half the desktop that is usually on monitor A, and on its left half the desktop that is usually on monitor B
- Other than this extremely strange behavior, I can still use my desktop
- After a reboot, both monitors are back to normal function
Please find attached the relevant dmesg.
