Menus are truncated at the bottom on Windows 11

[jihmailed@…]

Jonathan Jih reports that menu panes are truncated in ChimeraX 1.4 on Windows 11 (original bug report #7103 comment 6) so menu entries at the bottom are not visible.

   A more impactful issue is there also appears to be some drop-down
   menu/right click menu UI bugs with v1.4. Upon first launching a blank or
   restored session, drop down/right click menus are truncated (please see
   image below). On the very top toolbar (File / Edit / Select etc.) this can
   be remedied by either reclicking the menu item or hovering over to an
   adjacent tab before hovering back. On the dockable toolbar elements, there
   seems to be no way to get the full length menu to show. For someone like me
   who isn't familiar with all the (great) features you guys have added, this
   makes hunting features/exploring a bit difficult.

This is probably a Qt 6 bug specific to Windows, possibly specific to Windows 11. Maybe the menu panes are not being resized when our code adds new entries to the bottom (e.g. the Tools menu, or context menus).

I tested ChimeraX 1.4 menus on Windows 10 and did not observe any truncated menus. I checked the Tools menu and the Toolbar context menu (right click) and both displayed correctly.

We should test on Windows 11. If that works then perhaps Jonathan has changed the font size or default font ChimeraX uses on his Windows computer.

Installed 1.4 and a 1.5 daily build onto my Windows 11 machine. Created a session and opened it -- works on my machine.

Jonathan have you configured Windows 11 to use some non-default fonts? Is your default language in Windows English? What is the display scaling you are using (set in Windows system preferences for displays)? Since Zach does not see this on Windows 11 it is very likely something about your specific Windows 11 configuration.
