clearly bugs in your GPU driver. You can't expect them to support directdraw very well. Change config > display method if it's frustrating your debugging. There's also possibly a very old lurking bug (in desmume or bug in driver that's brought out by quirks in desmume's opengl renderer) which can destabilize the gpu driver. So this problem might go away if you change to softrasterizer. Tip: set softrasterizer cpp file to optimized even in debug mode and you can avoid the speed hit (of course the CPU emulation is still super slow)

Changing Display method to OpenGL, solves this crash.
