Sounds like a scaling issue with your os/DE and display resolutions.

What display factors have you set, what display dimension?
Comment 2 terra 2025-10-10 03:47:07 UTC
Scaling 100% and display is 1366 x 768

Scaling 100% and display res : 1366 x 768

supported display are min 1280 x 800 [1], but menus should not extend out of display at 768px (don't that I recall at 1024x768 on Win builds), guess it could be an issue specific to the kf5/kf6 os/DE vcl plug-in's handling of menus. 

Are you able to change over to the "gen" or the "gtk3" vcl plugin and retest? Done with the SAL_USE_VCLPLUGIN environment variable, or see Ask How-to:

@Michael, any perspective here for use of diminutive display with the kf6 (cairo+wayland) plugin?

For kf6, a native Qt menu gets used.

That sounds like the Wayland-specific Qt issue https://bugreports.qt.io/browse/QTBUG-137955 .

-> Closing as NOTOURBUG

Please feel free to reopen if you also see this on X11/XWayland, e.g. when starting LO with environment variable QT_QPA_PLATFORM=xcb .
