--- Comment #11 from lekto (lekto at o2.pl) ---
Same problem here. It happens when I run looking-glass [1], but not everytime.
I tied downgrading my kernel from 5.3.1 to 5.2.11 (I'm pretty sure it worked
then), downgrading mesa from 19.2.0 to 19.1.7 (I'm sure it worked with
19.2.0-rc) and downgrading my firmware to 2019-09-23 (oldest in repo).

When it happens looking glass starts blinking and sometimes my other monitor
stuck that I can only move cursor on it.

Spec:
Gentoo ~amd64
Ryzen 1600 (other have Ryzen too, coincidence?)
Linux GPU: R7 240 (with radeon driver)
Windows GPU: RX580
ASRock X370 Gaming X
