Stars! UI glitches out & fails to render when opened with OTVDM on windows 11 version 24H2

[Bertie690]

Describe the bug
When launching Stars! and opening a game (existing and newly created) with Windows 11 version 24H2, the UI proceeds to have a really bad day.
Most modals in the ship pane and scanner view are hidden until first selected (only showing up as whiteness), the production estimator constantly flickers like mad and the message pane just vanishes sometimes.
A few other people in the Stars! discord also reported having issues with this since updating to 24H2.

Expected behavior
Not to look like an epileptic light show crossed with a modern art piece.

Screenshots

From folks on discord:

Environment
Windows 11 Home Version 24H2 (Did not break before update)
Everything worked fine before updating; it's only after the update that everything started breaking.

Additional context
The actual bootup process, as well as all of the dialog & popup boxes look completely normal; it's only the game's actual UI elements that bork.
I even uninstalled and re-installed OTVDM to no avail.

I could not seem to get a trace file output for the life of me.

Auto HDR is off btw.

The last commit on #1482 works around this. 24H2 has removed all the win31 style compatibility code and that causes the production list box to be the wrong size. The program keeps trying to correct it which creates a wm_paint message storm which blocks the toolbar and message window from ever getting their paint messages. The changes disables the windows automatic listbox sizing.
