Summary 08789: Enter key randomly "gets stuck" after toggling Full Screen
Description Sometimes, after pressing Alt+Enter to toggle Full Screen mode, MAME acts as if the Enter key got stuck afterwards, so you can toggle Full Screen again by just pressing Alt alone.
Steps To Reproduce - Run any system.
- Press Alt+Enter.
- Press Alt alone and see if it toggles Full Screen. Else, press Alt+Enter and try again.
- Tap enter to get things back to normal.
Additional Information Randomly happens to me on two very different computers. Other people have experienced this issue, as well.

Another similar issue happening since some previous versions.
Linux Ubuntu 20.04.6 GT 640 driver 470.
Randomly happen when using an controller ( PS4 DS4 ) with any button exactly if using OSD menu.

Press an button to open OSD menu and move cursor to up or down using controller d-pad or analog left.
After was used the dpad or analog left to up or down for few seconds the cursor move to up or down as if was holded d-pad or analog left, but not any input from controller.
Not is possible enter any input from controller or keyboard for several seconds.
That strange bug happen much when selecting an bgfx shader at point to stop it need wait for several seconds or press up and down several times in sequence and even trying press in keyboard ESC, Enter and TAB not works.

Hello Robbert. All good with you ?
I not remember exactly if had happened before april, but since april 2023 to november that bug have happened several times here with me.
Is as if an internal task controlling inputs goes in loop and not finish process code thus any input done is holded.
If has an delay to render OSD graphic menu or when changing shaders have chance the bug will happen.
Well ... I will from now using opengl instead vulkan for see if happen again.

Yeah, this has happened for a long time. It's infrequent, but weird when it does.

I've never been sure if it's a MAME bug or some general Windows issue though (Win10/11 are still rough, if we're being polite)
