37 I upgraded yesterday from 5.7.4 to 5.7.5. I hoped the problem I have had
38 been fixed, but no. If I switch desktops too many times, or too often or
39 something, the desktop becomes unusable until I reboot (I haven't tried just
40 restarting xdm). It flickers rapidly, bits of one desktop are shown in the
41 middle of another or on a blank background, and it's hard to see just which
42 is the currently active desktop.
43
44 This may be a bad interaction with the xorg-driver for my AMD GPU, which has
45 only been on the market for about a year. Though sys-firmware/amdgpu-ucode
46 hasn't changed since June.
