Map rendering lost when switching apps

[dotcs]

I'm using the PWA app on Android. Sometimes, I guess it happens when the smartphone is short on memory, the map rendering is lost when switching between apps. So a typical scenario that I have experienced multiple times is that the PWA works fine but when I switch to my podcast player and later back to OsmGo, I can only see the control buttons and my location but not any map or any markers on the map.

I'll try to make a screenshot next time this happens and attach it to this issue. see below for a picture

Has anyone else experienced those issues?

I'm using a Samsung A31 with Android 11 and the Brave Browser (Brave 1.39.123, Chromium 102.0.5005.125).

I found an issue in the mapbox-gl-js repo that might be the root cause for this issue.

Chrome fires a couple of error messages in the console when this issue occurs:

WebGL: CONTEXT_LOST_WEBGL: loseContext: context lost
