Retroarch menu is not being hidden while playing games -

I have a strange issue - when I launch the Nestopia core the RetroArch menu stays on the screen as an “overlay” on top of the game - but the control switches over to the game totally (i.e. I can play the game fine, it’s just that the menu GUI from Retroarch is frozen on screen) - any idea what setting I can change to tweak this?

Here is a screenshot of what is happening:

Oh, also a little more info - I’m use SDL2 + RGUI on Ubuntu, installed Retroarch from the package

Can you try any other video driver? SDL2 is pretty much a last resort, and as such, doesn’t get much testing.

My graphics chipset is Intel 945GSE so only other video driver that works at all is gl1 (xvideo crashes on launch, no Vulkan or gl1.4+ support).

but with gl1 I can’t get any interface to work with retroarch - RGUI doesn’t work (crashes on launch - maybe doesn’t support GL 1?), switching to the gl based interface seems to work at first, but no input mechanisms seem to work when using GL interface with GL1 (keyboard/mouse unresponsive)
