F12 causes black screen using OS4.1FE

[Snake79]

Hi. I have black screen using attached config (os41fe) when trying to open settings window by 'f12'. After that, i can only back to desktop with 'escape' and close emulator by 'alt+f4'.
That is happening when using Fullscreen (1920x1080) with Low latency VSync (or without it).
When using Full-window (1920x1080) with Low latency VSync everything is ok.
Tested with official 3.3.0 and 3.4.0 betas.
PS. I'm using Win10 1607 (14393.222) and latest GeForce drivers (on previous was the same).

Both logs needed. (But I think you need to duplicate it using without OS4 for me to actually care unless it is something simple, sorry)

Hmmm, sorry, but i don't know how to create logs when i can't access settings window (because of black screen).
But have a simple test:
Pick quickstart A1200 basic config, change Display Fullscreen 1920x1080 and Native Fullscreen. Run emulation and press F12 -> blackscreen.
Config attached (os independent).

Load your config, tick Paths panel logging option, then start emulation. Quit with alt+f4 when black screen appears.

Happens to me also, A workaround (that works for me) is to open a folder or text file etc before launching WinUAE, then when you press f12 and get the black screen you can alt+tab back to the desktop and alt+tab again to bring up the WinUAE settings window.

Logs based on test.uae config (basic qs a1200).
blackscreen.7z when using 1920x1080 Fullscreen and
ok.7z when using 1920x1080 Full-window.

DaveMB's workaround is working (alt-tab). Thanks meantime.

Does switching Display panel buffering option to double (or no buffer) change anything?

Sadly, no, BUT switching refresh rate to 50Hz PAL works (and 60Hz NTSC not). Very strange... With Full-window everything is ok...

Can confirm this works for me also.

I reinstalled GeForce drivers to official oldest one for W10, but without success. I tried WinUAE 3.2.2, 3.2.0, 3.1.0 and the issue is the same. I am sure, that a few months ago everything worked fine, before Anniversary Update of W10. So i think, that the issue might be related to some another W10 "new feature"...

[Snake79]

I discovered that when you run WinUAE in compatibility mode with Windows 8 everything is working as it should. The settings menu (f12) appears in Fullscreen mode as before (Anniversary Update of W10).
PS. and if that can help in something, when using DirectDraw f12 is working too (without compatibility mode), without blackscreen...

Attach test.uae works normally here.

Windows 10 Insider build 14942. GTX980 SLI 373.06. Monitor is ultra-wide g-sync. All of these probably makes this quite invalid test..

[Snake79]

Maybe they (MS) have changed something between the builds... Will wait for update (slow ring) and check... Thanks.
