Description René 2020-12-14 11:48:15 UTC 
SUMMARY
This seems like a functionality regression. Previously I could select a text, start dragging it, then with ALT Tab change to another applicaton window and there drop the string in that window. I don't see the point why I should always contaminate the clipboard with these routine operations. Work around is slow and needs more coordination and finding the right one, namely to drag the string to the desired task tab in the task manager which will make it change the focus there. When that still works, why not ALT Tab like before?


STEPS TO REPRODUCE
1. Select text string in task A
2. Start dragging while changing to previous task using the ALT + Tab key combination. 

OBSERVED RESULT

ALT Tab will no longer change to previous task during a drag operation.

EXPECTED RESULT
ALT Tab will also change task while doing a drag operation.

Works for me dragging text in Firefox to Kate in Plasma 5.20. Which apps are you using where this is broken? Does it work in Firefox and Kate for you?

The dragging is not the issue here, but what it inhibits, namely to use of ALT + TAB to change task. ALT+TAB from FF to Kate does not work here, but curiously from Kate to FF does.

Weird, works for me.

Are you using X11 or Wayland? If it's X11, then the bug will be in Firefox.

I just noticed that also Thunderbird shows the same behaviour. If I remember well Thunderbird, Firefox are GTK applications but I could not reproduce the same behaviour (or lack thereof) in other GTK applications like gEdit.  I therefore close this issue and report it elsewhere.
