If it's crashing we should get a drkonqui window which has a backtrace, could you attach it please. It's not crashing (so no backtrace). The process is still running after "visually disappearing". It reacts to a SIGTERM (no need for SIGKILL). Also, the signal handler still writes "User defined signal 1" to the console if I send a SIGUSR1 to the process. While playing around with timing: when I shrink the window after the wallpaper has already been painted but the panel is still loading, it isn't turning black but continues loading (including correctly scaling the wallpaper in the end). However, removing the panel, restarting plasmashell and shrinking after that still leads to a black screen. I could send you a ltrace and/or strace of the starting/resizing/"hanging"/killing cycle if you think that could help. Is this behavior still present in current Plasma versions?

Created attachment 94365 [details] kquitapp5 plasmashell; sleep 3; plasmashell 2>> plasmashell.err I'm running an up-to-date Archlinux amd64 installation with KF5, Applications 15.08 and plasma 5.4 in a libvirt created KVM VM with qxl/spice and vdagent. When enlargening the viewer window on the host, plasma adapts to the new resolution and the desktop uses a higher resolution. But when shrinking the window, the desktop turns black (only plasma, other applications as well as kwin handle it fine and continue working). The plasmashell process is still running. Killing and restarting it brings back a working shell. The configuration is basically standard (just added IM applet). No KDE4 has ever been installed in this VM. Creating a new user in the VM (to clear any config) shows the same result.
