Just confirming that the patch from Andreas (attachment 1715 [details]) works for me under SDL 2.0.3 with xmonad.

Confirming that the patch in this ticket fixes the full-screen switching for dosemu2 on ubuntu-16.04. Note that I am not using xmonad, so this bug appears to be generic.
"Using an application in portrait orientation, turning off the device would
dispatch SDL_APP_WILLENTERBACKGROUND, then SDL_APP_DIDENTERBACKGROUND then
lock the screen.
However, rotating the application the application to landscape, then turning
off the device would incorrectly dispatch SDL_APP_WILLENTERBACKGROUND,
SDL_APP_WILLENTERBACKGROUND, SDL_APP_WILLENTERFOREGROUND and then
SDL_APP_DIDENTERFOREGROUND before locking the screen. You can imagine how
this created trouble :)
It appears this occurs because (on this application) turning off a device
when in landscape is triggering a resize. The resize logic in SDLActivity
triggers a resume.
This patch has resolved the issue on my device:
It prevents the dispatch of (improper) FOREGROUND events when locking
the device, but we get still events when the device is turned back on
and unlocked."
This gracefully recovers when a device format is changed, and will switch
to the new default device if the current one is unplugged, etc.
This does not handle when a new default device is added; it only notices
if the current default goes away. That will be fixed by implementing the
stubbed-out MMNotificationClient_OnDefaultDeviceChanged() function.

Moving some variable declarations to the top of Android_SetScreenResolution()
* alsa hotplug thread is low priority
* give a chance for other threads to catch up when audio playback is not progressing
* use nonblocking for alsa audio capture
There is a bug with SDL hanging when an audio capture USB device is removed, because poll never returns
These don't have to be power-of-2 sizes anymore because of SDL_AudioStream,
and the new resampler, but also, many platforms don't give you power-of-2 DMA
buffer in the first place!
