KDE Plasma Wayland - Monitor DPI Below 100% Effects Window Title Bar Display:
DESC:
Window Titlebar UI buttons stop correctly displaying
on the top right-hand side corners with DPI settings below 100%
NOTE: Issue only shows up on screen/monitor who's DPI setting falls below 100%
DPI settings at 100% and higher do not cause any issues
Graphics Affected:
Window Titlebar Minimise, Maximise, Close - UI Button's
DE's Bug Appears In:
Plasma X11: N/A
Plama (Wayland) Xwayland: YES
Plasma (Full Wayland): YES
REPRODUCIBLE: YES
1. Settings > Display
2. Choose a/the screen/monitor to have a DPI lower then 100%
3. Set a value lower than 100% for the DPI
4. Press Apply
5. Open an app up, example KATE
EXPECTED BEHAVIOUR:
To see all the windows and all their respective related UI stuff change in a
scale proportional to the stated DPI
WHAT DOES HAPPEN:
Any/All windows open will have the above stated UI buttons hidden from view in
their titlebar
NOTE: The Window Title bar options will become visible if the mouse pointer is
moved over them
NOTE 2: If you have at least 2 monitors, and at least one of them has either
not had its DPI changed from the default OR
has a DPI Greater than 100%, then moving the window that has the hidden
UI elements over to the screen/monitor
that has a DPI or 100% or greater DPI, one will immediate see the
windows titlebar elements again
Also vice-versa, moving the same window back to the/a screen/monitor
who's DPI is set to below 100%, once again
the windows titlebar UI elements will again become invisible.
NOTE: Changing any of the below also had no effect, with the exception that
changing 'Window Decorations' from Breeze to
Plastik meant that NO UI elements at all were displayed in a windows
titlebar (the ones on the left-hand side) until
a re-boot was performed.
Global Theme: Breeze Twilight
Application Style: Breeze
Plasma Style: Oxygen
Window Decorations: Breeze
