Tested and it works fine here, although on exit I get an assert

BLI_assert failed: /src/blender/source/blender/gpu/intern/gpu_context.cpp:153, GPU_context_discard(), at 'ctx->framebuffers.empty()'

The assert on exit could be fixed with: D3919
Not sure if that patch still works.

@Gottfried Hofmann (gottfried) Is this still an issue for you?
