SUMMARY
There is a pixel gap at the right edge of the screen after maximizing a window.
It gets annoying especially when I'm playing videos in full screen mode (VLC).
And I find it concerned with DPI scaling factor.
STEPS TO REPRODUCE
1. Set scaling factor to 1.4 in 'Display and Monitor'.
2. Open Dolphin (or any other built-in apps) and maximize the window.
OBSERVED RESULT
A vertical gap, of one pixel, appears at the right edge, not at the left nor
other directions. The pixel colors indicates my background wallpaper. See the
attachment.
EXPECTED RESULT
No such a gap.
SOFTWARE VERSIONS
(available in About System)
KDE Plasma Version: 5.12.6
KDE Frameworks Version: 5.48.0
Qt Version: (I don't know how to get the version)
Kernel: x86_64 Linux 4.18.9-100.fc27.x86_64
ADDITIONAL INFORMATION
My screen is 15.6' 1080p. I've tried scaling factors 1.0, 1.3 and 1.5, they all
work fine. And it seems a problem only with Qt apps, since my Chrome isn't
affected.
