Destroying SDL_Renderer in app background event with the intention to restore it in foreground event leads to crash

See original GitHub issue

Versions

Python: Python 3.6.6
OS: built on ubuntu 18 lts, happens on android 7 in multiple variants
Kivy: not used
Cython: happens without Cython as well

Description

What happens:

Destroying SDL_Renderer in app background event with the intention to restore it in foreground event leads to crash. I tested this on multiple devices, so this is most certainly not a GPU driver bug, but something in either p4a’s wrapper or SDL2’s SDLActivity that is broken.

The crash happens when you go back into the app inside the wrapper with access to address 0x8 before the app resume event / custom app code happens, so right before control is returned to my own app code.

There is a small chance of the crash not happening, and if it doesn’t, everything will work fine from then on in any followup background & resume events. So it seems to be some sort of race condition.

Why would anyone want this to work:

The reason to do this in the first place is to avoid buggy GPU drivers that don’t keep the 3d context around, so accessing the SDL_Renderer after background & restore would lead to a crash - hence, the dumping and recreation to avoid that. However, with p4a this doesn’t work right now due to this crash.

Why aren’t all apps affected by this:

I’m pretty certain kivy is unaffected because it neither uses SDL_Renderer, nor seems to destroy & recreate the context in such a way.

buildozer.spec

not used, but my requirements are not including kivy, just plain SDL2

@inclement yes the crash is definitely still happening, although not triggered only by renderer change (that just seems to make it more likely). I was simply busy with other things, but before I release my app I’ll have to debug this and find out. It’s some race condition with leaving & coming back

I suspect it’s a bug in either SDLActivity.java, PythonActivity.java or SDL2 native code. Can’t say more without debugging it deeper
