Hi, I am sending a couple of patches I needed to apply to make the SDL2 GUI work reasonably on Debian Sid, which recently switched from SDL1.
The main issue is that the QEMU window stops updating when it is minimized, or after a virtual desktop switch. Then, there are some regressions due to recently added terminals in multiple windows, and some issues with fullscreen mode and window scaling. I am using MATE desktop 1.18 and SDL 2.0.6.
