Black screen after resuming SDL2 application on Android

[MVoloshin]

Hello! I've tried to build Bochs for Android with SDL2 (UI code looks like this: https://github.com/bochs-emu/Bochs/blob/master/bochs/gui/sdl2.cc).
Application runs fine, but if I minimize application and then restore it or put my screen to sleep and then wake it up - I just see black screen. What could be the reason? If necessary, I could provide apk and logcat output

I'm seeing the same issue. Code which worked in with .8 isn't working with .11

Yes, apk and logcat would be helpful.

I checked the diff between .8 and .11 for Android and the only changes were version number and copyright date, so more clues would be great.

Are you able to reproduce it with the testsprite SDL test program?

I tried with testsprite2 on a Samsung Galaxy Note 8 and it works fine here, both bringing up the task switch UI and going back to the home screen and then back to the app.

I retract my comment; turns out I had made a small change between versions that had an outsized impact. Sorry.
