[uwp] testoffscreen segfault at start-up #7632

Open madebr opened 1 year ago

Output:

Exception thrown: read access violation.
**WINRT_GlobalSwapChainBackgroundPanelNative** was nullptr.

Call stack:

It's happening here: https://github.com/libsdl-org/SDL/blob/0467301baf57389d96fafbe169fb07f4c10169bc/src/render/direct3d11/SDL_render_d3d11.c#L799

testoffscreen.exe, built for "normal" Windows runs fine on this system.

Is this still happening?

Yes, with an identical stack:
