I place panel to the right edge (sorry, didn't check left side) of screen. When I restart, that panel placed right, but with one pixel gap to screen edge. If I press mouse button there, click goes to desktop area. If I open panel settings and drag "Screen Edge" button, panel snaps to edge well, but after restart gap would be again. Reproducible: Always Steps to Reproduce: 1. Place panel to the right edge. 2. Restart. Actual Results: See one pixel gap to the right of panel. You may click right mouse button and get desktop menu, not panel one. Expected Results: Panel should be snapped to right edge.

Seems it's not restricted to just the right edge *** This bug has been marked as a duplicate of bug 339297 ***
I have checked 4 placements, so my conclusion https://bugs.kde.org/show_bug.cgi?id=339297 was solved but vertical right placement still has 1 pixel gap.

Git commit 975e5009c176eb378daa5c8f74cd4cffb64ff459 by Bhushan Shah. Committed on 26/03/2015 at 15:50. Pushed by bshah into branch 'master'. Fix one pixel gap between screenedge and right placed vertical panel Appearantly right() / bottomRight() / topRight() returns values with 1 pixel x off for historical reasons and hence 1px gap. This causes the autohide panel not hiding automatically.
