Screencast of XTerm resize attempts
SUMMARY
XTerm + Wayland + Screen Scaling + "Obey geometry restrictions" behaves
strangely.
(Not sure whether the component "xwayland" is correct here ...)
STEPS TO REPRODUCE
1. Start from a fresh openSUSE Krypton, change session to use Plasma on Wayland
2. Configure a screen scaling of 120%
3. Add a KWin rule to obey geometry restrictions for XTerms, like this (from
kwinrulesrc)
[5f52965d-a159-400c-bc33-aa5d89da6d97]
Description=Application settings for XTerm
clientmachine=localhost
strictgeometry=true
strictgeometryrule=2
wmclass=XTerm
wmclassmatch=1
4. Open an XTerm and move it into the right-hand side of the screen
5. Attempt to resize the XTerm
OBSERVED RESULT
The XTerm window does not allow to resize to all sizes - instead only to very
small window size or very large ones. It seems that KWin applies some
completely strange resizing restrictions and not only (what I would expect) the
resize-by-character restrictions.
See also attached screen cast, which shows it better than I can explain it.
EXPECTED RESULT
XTerm window resizes smoothly and without jumping between allowed sizes.
