No image, only sound when high contrast is enabled in Windows 10

[PannenkoekenNL]

When I have my high contrast theme enabled in Windows mGBA doesn't display video/image, only sound. I have tried it multiple times and sometimes it just gives black screen and sometimes the screen freezes. This happens with all ROMs I tried. I am using the latest 0.4.0 build on Windows 10 64-bit. When I disable high contrast mGBA is working perfectly. VBA-M is working perfectly with high contrast enabled btw.

I can't reproduce this. Does it still reproduce for you?

[PannenkoekenNL]

Yes. Try going to the settings apps > personalization > colors > high contrast settings > choose 'High Contrast Black'.
I am using mGBA 0.4.1

Please use a nightly.

[PannenkoekenNL]

Same problem with the nightly.

I still can't reproduce this. Does it happen with the Software (Qt) display driver?

[PannenkoekenNL]

No, it is only the mgba screen that turns black

[endrift]

I meant the display driver for how mGBA puts the GBA screen into the window. It's in settings. OpenGL and Software.

[PannenkoekenNL]

Ah, when I select Qt it works perfectly.

[endrift]

Ok, it might be a problem with your graphics drivers and not mGBA, then. What GPU?

[PannenkoekenNL]

NVIDIA GeForce GT 750M with the latest drivers.

[endrift]

Hm, I have a GTX 1080 with latest drivers, so that might not be it. I'm really not sure unfortunately :S

What version of Windows 10 do you have? Need build number.

[PannenkoekenNL]

1607, the same happens with the previous version (1511).

[skidgfx]

OpenGL passes on 1511. It's a miscellaneous case. I can't replicate. Can anyone else?
Suggest: Debug on external HDD Fresh copy on Windows 10 and fresh install of everything. If problem persists post back. If not, then you need to find what the bug is on your system.

Over at GBAtemp, KleinesSinchen did some testing on Windows 10 you guys may want to take a look at:

Make sure to try OpenGL (force 1.x).

It's worth noting that the non-1.x version requires EXT_framebuffer_object, which many OGL2+ cards have but it's only a safe bet in 3+. The card in question does not support 3 nor, likely, EXT_framebuffer_object, hence the issues at play. And I don't detect that very well.

I can't reproduce this error, using the same 'High Contrast Black' theme applied on Windows 10 ver 2004, mgba ver. 0.9.0.

@PannenkoekenNL are you still able to reproduce this? If so, can you upload a zip from File > Report Bug on a modern version of mGBA?
