Summary 08645: UI: Bgfx: Crash when switching to/from fullscreen while tilde menu is on-screen
Description It seems that certain options from the Tilde menu are somehow causing MAME to crash if they're on screen while pressing Alt+Enter in Windows.

Some example error logs are attached, as well as a pop-up error that MAME displayed only once.
Steps To Reproduce -Start any driver in MAME.
-Press the Tilde key.
-Select "Screen Vert Position" option or below.
-Press Alt+Enter, MAME may crash.
-If it doesn't crash, press Alt+Enter again. (Moving the selection up/down might work as well?)
Additional Information Tested with Opengl and Vulkan backends.
Might be random, but the chain-related options ("Window 0, Screen 0 Effect x" and below) seem to have a better chance of crashing it.

 Looks like part of a wider problem.

I used
>mame pacman -video bgfx (my default backend is d3d11 and my default is Windowed).

After playing the game, I pressed Tilde and selected the "Screen Vert Position" but didn't change anything.

Pressing Alt Enter worked, so I pressed it again - worked again. Then I pressed the Down key to choose another slider, and it crashed.

C:\MAME>mame pacman -video bgfx
