I suspect so. It happens on one of my desktops, having Radeon 6450
card. If I unplug the HDMI to the second monitor before resuming, it is
generally OK. Causes similar problems with a reboot.
OTOH, not an issue on a newer desktop having Radeon 8510G graphics.

I'm running openSUSE 15.2 beta, with Plasma. Has not cured it.
