Description Christian Herenz 2016-06-18 13:57:53 UTC
I have the panel on the bottom on the screen and set it to autohide.   I configured 4 virtual desktops in a 2x2 arangement.
I configured the screen borders to allow dragging of windows to other virtual desktops when coming to the screen borders.
Moving a window to the bottom edge of the screen where the hidden panel is, often results in the window being not dragged to the virtual desktop below, instead it is dragged (after some flickering) to the same virtual desktop. This happens in 90 % of the attempts, and I can not reproduce why it works or not.
This does not happen when the panel is not set to authohide.

Reproducible: Sometimes

Steps to Reproduce:
1. Configure 2x2 grid of virtual desktops.
2. Configure panel to appear on the bottom of the screen and set it to authide.
4. Configure the screen borders to allow dragging of windows to other virtual desktops.
3. Open a window  and drag it to the bottom of the screen.

Actual Results:  
The window moves is dragged to the top of the same virtual desktop.

Expected Results:  
The window is dragged to the virtual destkop below the current virtual desktop.

Dragging windows to all other 3 borders (top, left, and right) works as expected.

Just a ping. Still is the case in 5.8.7 - can anyone please try to reproduce it?
Comment 2 Alexander Mentyu 2018-03-01 11:09:27 UTC
Cannot reproduce in:

Plasma: 5.12.2
Apps: 17.12.2
Frameworks: 5.43.0
Qt: 5.10.1
Kernel: 4.14.22-1-MANJARO
OS: Netrunner Rolling

Here I show the glitching behavior. Note, it doesn't always happen .. so I think it is some timing issue.

The video shows the following (movement with the pointer was always down, with natural speeds, I can not reproduce the glitches by forcing a specific fast or slow speed):

1. [00:00 - 00:05] Window is moved to the bottom desktop, and appears at the bottom of that desktop.  Expected behavior: Window appears at the top of the bottom desktop after being moved to from the top desktop. 
2. [00:05 - 00:15] A couple of OK movements for window dragging between top and bottom desktops
3. [00:15 - end] Window is moved to the bottom of desktop and appears at the top of the same desktop. Expected behavior: See [1]

This is Plasma 5.14.5 in Debian Stable.  I.e. significantly later than where someone claimed that he can not reproduce it.  I stress, that I sometimes can not reproduce it either.  It is very erratic, but it should not happen at all!
