Description Michal Srb 2012-06-06 16:01:53 UTC

I have switching virtual desktops enabled when cursor touches edge of screen.
It normally works, but doesn't when the mouse is drag&dropping something (file, text, ...).
According to bug #86998 it was implemented and should work.

Reproducible: Always

Steps to Reproduce:
1. In System Settings, in Workspace Behavior/Screen Edges set "Switch desktop on edge" to "Always Enabled".
2. Drag&drop e.g. piece of text to edge of screen.
Actual Results:  
The virtual desktop is not switched.

Expected Results:  
Switch the virtual desktop.

works here.

What version are you using? When did you start to notice it?

depends on the drag source but at least for the kwin implementation qt triggers insufficient dnd ckient messages (iirc i commented on this on another bug than the actual dupe)

that would make sense - I started to drag from Firefox

iirc more, only immediate reaction would work (the message is only sent on enter, not move and we can't push back the grabbed pointer) - though i don't know whether Qt is just "broken" in this regard or it's a problem with the 1px wide border
