Bug ID: 521066
Summary: Buttons along top of large, hi-res screen cannot be
clicked with fractional scaling enabled
Classification: Plasma
Product: kwin
Version First 6.6.5
Reported In:
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: [email protected]

Target Milestone: ---
DESCRIPTION
Since upgrading to Fedora 44 (and only since, so this is a regression), I've
noticed that on my large monitor (G95NC, 7680x2160, 60Hz), the menubar becomes
largely unclickable at the top of the monitor (only when the bar is against the
top of the monitor) with fractional scaling enabled. The window's source
doesn't appear to matter, it happens in Firefox, Chrome, KDE settings, etc. It
does not appear to be consistent across monitors, and the same machine with
multiple monitors can have (or not) the problem independently on each monitor,
for reasons I can't quite understand.
STEPS TO REPRODUCE
1. Set fractional scaling to non-100% number
2. Move or tile window so that its titlebar and decorations are at the top of
the screen
3. Attempt to click the titlebar (e.g. to close the window or change tabs in
Firefox)
OBSERVED RESULT
You cannot click in most places. Instead, there's a narrow (I mean perhaps 10
pixels) horizontal band perhaps 2/3 down the titlebar which can be clicked and
which shows (e.g.) highlighting of the button, but nothing else works.
Note that this can be addressed, it seems, by changing the scale to 100% in
Display Config, and then back to (e.g.) 125%. But it appears to return after
restart.
EXPECTED RESULT
Clicking works as expected.

ADDITIONAL INFORMATION
Sorry, this is a weird one. Smells related to 505225, but doesn't have exactly
the same flavor, so I re-submitted.
