Description Bernie Innocenti 2019-06-18 16:21:28 UTC 
SUMMARY
The Tilix terminal emulator is a GTK3 application with client-side decorations. Like many terminals, it adjusts its window size to an even number of character cells.

Dragging a Tilix window works normally with KWin in X11, but has a surprising behavior in Wayland.


STEPS TO REPRODUCE
1. boot into a Plasma Wayland session
2. open Tilix (I have version 1.9.1, in case it matters)
3. drag it around from the title bar

OBSERVED RESULT
The Tilix window grows by a few dozen pixels every time you repeat step 2

EXPECTED RESULT
The window size shouldn't change

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.16.0
KDE Frameworks Version: 5.59.0
Qt Version: 5.13.0rc3-1

BTW Konsole in 19.08 (unreleased) will have the same tiling features. :)
Comment 2 Vlad Zahorodnii 2019-06-18 18:16:30 UTC 
If I'm not mistaken, this bug is fixed in master (which means the fix will be available only in Plasma 5.17).
Comment 3 Nate Graham 2019-06-18 18:18:03 UTC 
Is it easily backportable to the Plasma/5.16 stable branch?
