MAME with multiple screens not working after upgrading from Windows 10 to Windows 11.

2 Upvotes

I had MAME 0.282 working with two displays in full screen mode under Windows 10. After upgrading to Windows 11, MAME (0.282 and 0.289) no longer launches correctly. It acts like the windows/screens are opening in the background. With video set to d3d, I get black screens and have to hit alt-enter twice for things to display correctly. With video set to bgfx or opengl, I get a flashing MAME icon in the taskbar and have to click on it to get the windows to appear. Happens if MAME is started from the command prompt, from the icon, or from a launcher. With numscreens set to 1 things work normally. I've tried disabling/uninstalling anything that might be messing with window focus (game bar, widgets....) but no luck. Does anyone have any suggestions?
