I assume from these results that the gui_grab is never set to 1 when having

Maybe that's why the sdl_grab_start() is called so often.

It seems that the condition in sdl_grab_start() (SDL_WM_GrabInput(SDL_GRAB_ON)
== SDL_GRAB_ON) is never fulfilled, otherwise the gui_grab would be set to 1.
But the cursor is actually grabbed in windowed mode, otherwise I would not be
able to click somewhere with the guest-windows-cursor.

This might be a SDL limitation which does not show up everywhere. Here
it's fine e.g.

The logic dates back to "Handle SDL grabs failing (Mark McLoughlin)",
6bb816031f. Maybe we can solve that issue without relying on the
obviously unreliable return value. Need to reproduce that one as well,
though.

Please check if

git://git.kiszka.org/qemu.git queues/sdl

fixes the issue for you. Namely reverting the above commit should do the
trick. I obsoleted that fragile patch in my series.

Thanks,
Jan



Hi Jan,

I will test this on monday. Can you tell me how I can merge that into my cloned main qemu repository? I'm quite new to git.

Thanks.

Best regards,

Erik
