graphics distorted in wayland session
randomly, some graphical glitches pop up on the screen. example is attached, graphical glitch can be seen on the top left part of the screen and it cannot be seen on screenshot (prtscrn). the distortion changes as the other parts of the screen change as well.
even though on the screenshot there is dash-to-dock extension, same thing happens with extensions disabled.
fedora 31, amdgpu, two hidpi screens. latest gnome and updates.
