Right now I'm battling the rough edges around the RX 5500 XT support. If you try and use 3 monitors it reliably crashes. You can kind of make it work by manually setting monitors.xml to a low resolution on them or a low refresh rate before you add the third monitor, but that only seems to work if you add the monitor at runtime. I copied the same monitors.xml for gdm as well so no clue what during initialization seems to be crashing it only if it's during boot. I've tried all the way up to DRM-next, mesa-git, latest linux-firmware and so far I'm stuck with 2 out of 3 screens. I've also got a new 3700X and that's been completely stable.
