When the panel disappears, do other windows disappear? Also is it x11 or wayland? (In reply to Vlad Zahorodnii from comment #1) > When the panel disappears, do other windows disappear? Also is it x11 or > wayland? My bad - it's X11. Other windows do not disappear but what I also noticed: in addition to panel, wallpaper disappears as well. Basically when it happens - all I see for a split second is a black screen and remaining window/s (In reply to Vlad Zahorodnii from comment #1) > When the panel disappears, do other windows disappear? Also is it x11 or > wayland? It sounds like plasmashell crashes. Can you get the backtrace of the crash? Run coredumpctl list plasmashell find the relevant entry, usually the last one and use its PID in coredumpctl gdb <pid> when gdb loads, type "bt" and post its output here (In reply to Vlad Zahorodnii from comment #4) > It sounds like plasmashell crashes.
