Description soee 2016-01-11 11:23:31 UTC

If we make our panel vertical (move it to the left screen edge) there are problems when resizing it. For egzample if we make it wider and wan't lower size after that (the same action) we can't. But if we  make few attempts increase/decrease size it starting to change it but there are visual glitches - please see attached viedeo.

Reproducible: Always

Steps to Reproduce:
1. Move panel to left screen edge
2. Make it wider
3. Try lowering size

Actual Results:  
We can't lower size or after several attempts the gui starts to flickering.

Expected Results:  
Panel should smoothly change size like it does when in horizontal mode.

Small update: i think this started to happen after upgrade to Frameworks 5.18 bit i'm not 100% sure.

There are also other visual issues when panel is in horizontal view like task manager items are missing spaces and this worked fine on Frameworks 5.17.

Comment 2 Darin Miller 2016-01-12 03:26:39 UTC

Confirmed with Frameworks 5.18.  I do not have 5.17 to try...

In my case I am unable to reduce height of panel on the top edge.
