RetroArch Android PPSSPP Core Standby Issue

[barfpony]

Using RetroArch and the latest PPSSPP core on a Pixel 3 XL. When running a game on the PPSSPP core, if the phone enters standby, then returns, RetroArch/PPSSPP will display a black screen. Sound and input seem to still be working. This happens with both gl and vulkan. This behavior only happens with the PPSSPP core. The only solution I've found is using the task switcher to switch away from and back to RetroArch, but that has no effect.

Sorry if this is the wrong place for this, it doesn't seem to be a RetroArch issue, since other cores work, and as far as I can tell the PPSSPP core is maintained by Henrik (thanks for the hard work, by the way).

Cheers!
