It doesn't crash for me, however it closes and re-open the RetroArch window.

It looks like the max framebuffer width is too low for this game as it sometimes seems to double its width. So for example at 640*480 the core sets a max width and height of 853*853:

flycast/shell/libretro/libretro.cpp

Lines 635 to 636 in f4f087a

	geometry.max_width = std::max(framebufferHeight * 16 / 9, framebufferWidth);
	geometry.max_height = geometry.max_width;

but then the game decides to double the width (1280 in this case) so the core has to set a new max width and reinitialize the video driver. I'm guessing that reinitialization could cause the crash in some cases?

No crash here either. It is expected that some games will change video settings such as horizontal pixel doubling. But this shouldn't cause a crash. It looks like a faulty GPU driver.
