Description MMDeveloper 2015-05-18 01:36:08 UTC

There is a small gap between the bottom of my horizontal panel and the bottom of my screen. If I "Unlock Widgets" and click on the wrench icon of my panel, then click on "Screen Edge" and re-lock widgets, the gap will disappear until I reboot. When I reboot, the gap is back until I click "Screen Edge" again.

This is a fresh install of Kubuntu 15.04 (plasma 5.2.2) and someone recommended I upgrade to plasma 5.3.0, which I did, and it didn't fix the problem. This may just be my mind playing tricks, but with plasma 5.3.0, the gap looks a few pixels larger.

Reproducible: Always

Steps to Reproduce:
1. Install Kubuntu
2. Unlock Widgets
3. Click Wrench Icon
4. Click "Screen Edge"
5. Lock Widgets

Actual Results:  
The gap disappears as the panel is 'moved' to the bottom of the screen. When I reboot, the gap reappears.

Expected Results:  
The gap should have remained gone.

The only modification I've made to the panel is adding a couple of icons next to the launcher, and I've ever-so-slightly adjusted the overall height to make the icons a tad larger. I'm using a different desktop theme but changing back to the original theme does not affect the issue.

Some additional information didn't occur to me worth mentioning (sorry I'm new to this). I'm on a Dell Latitude 17" touchscreen laptop with AMD gpu but using the non-proprietary graphics drivers.

I had the latest version of kubuntu that was before the official release of version 15 and this gap did not appear (same laptop, older version of KDE).

this is probably caused by an old oddity of QRect api for which rect.bottom() = rect.y() + rect.height() - 1

Now I have this in plasma 5.11.1 Neon packages on kde neon.
