Hi Chris, thanks for pointing me to the right direction. Unfortunately, it didn't work as expected, probably because I still don't get things right in my head ;)
However, I found a workaround that works quite well: I simply destroy my viewer before I get a context loss. I can still keep my scene so everything looks as before leaving the app. When going back into the application, I simply create a new viewer and everything works smooth :) Best regards, Martin Am Mi., 24.
