Dolphin window opens undersized
SUMMARY
When opening Dolphin in a maximized window, the right and bottom edges do not
fully reach the screen borders, leaving thin visible lines of the background
application (see the first screen recording).
Additionally, when navigating through certain directories, the Dolphin window
gradually shrinks by a few pixels at the bottom with each directory change (see
the second screen recording).
This issue occurs only on X11 when the global display scaling is set to 150%.
It does not occur at 100% scaling.
It appears to be related to an incorrect window size calculation that
accumulates over time when fractional scaling is enabled.
STEPS TO REPRODUCE
1. Set the display’s global scale to 150%
2. Open Dolphin
3. Browse through multiple directories (e.g. those shown in the video)
OBSERVED RESULT
- The maximized window does not completely fill the screen.
- The window height gradually decreases with each directory change.
EXPECTED RESULT
- The maximized window should fully occupy the screen.
- The window size should remain consistent when navigating between directories.
