emerge --info x11-base/xorg-server
I've just upgraded a bunch of packages including x11 proto and xorg, which also caused x11-drivers to be rebuilt.
Since then the GPU crashes any time i do something in xrandr, eg:
xrandr --output DVI-0 --off
Additionally the second screen only as brought up by X only shows the mouse, but no windows or anything.
Video card is Radeon 7700HD
Kernel is 4.15.7; downgrading doesn't help.
I'm not sure who's the culprit and I don't seem to be able to downgrade easily as x11-base/xorg-server-1.19.6 is no longer available and 1.19.5-r1 won't install due to convoluted deps.

I've just added xf86-video-ati-18.0.0 to the tree. Please give that a try. If it does not resolve the problem, please file a bug upstream at https://bugs.freedesktop.org/enter_bug.cgi?product=xorg&component=Driver/Radeon and link us to it here.

Same issue with xf86-video-ati-18.0.0. Will file a bug upstream when I have a moment.
