Description Egor Pavlov 2020-06-08 06:43:21 UTC 
Crash happens in RenderCopy/RenderCopyEx on window resize (since SDL 2.0.10). 
Just play with window size few seconds and you get massive SDL_RENDER_TARGETS_RESET flooding, that wasn't happens in 2.0.9 and before. x64 affected too. You may use this app for tests:

Setting up the "SDL_HINT_RENDER_BATCHING" to "1" helps if renderer created for  a specified driver.
