Hi, whenever I try to get a snapshot of the screen, ksnapshot window gets hidden and doesn't reappear after the snapshot is taken.
I have this misbehavior only if I use a three monitor setup. If monitors are only two, ksnapshot behaves normally. Do you know any workaround?

actually kgrab works without problems

Does the window appear in Alt + Tab or any other list of windows? It could be minimized.
Also, please check on other virtual desktops or activities as it could be hiding there instead.

No, there isn't in either places.
It does appear listed in the running windows of krunner, but if I click over "activate running window on desktop 1" it actually doesn't do anything.

That is quite unusual. This seems to be a KWin issue as such, so i'm going to move this to the KWin forum.
Can you please provide some information on the layout of your desktop, particularly in regard to the value of "$DISPLAY" from a terminal run on each screen, and the output of "qdbus org.kde.KWin /KWin supportInformation"?

cause ksnapshot to be hidden.
next from konsole run

Code: Select all

xwininfo -tree -root | grep KSnapshot

This will (hopefully) print a line like

The window should appear (and be managed) on DFP1
It still might explicitly or by rule bypass the tabbox, though.


-> Either the texture is void (try suspending compositing "Shift+Alt+F12", in case it happens again) or the window is falsely stacked below the desktop ("kquitapp plasma-desktop")
