I'm trying to use statementreply's replication steps. I'm not sure what I'm supposed to be doing instead. I'm getting weird results when importing a map while alt/tabbed out during a full process.
That's a super enlarged version of the F2 text as a background. I think that this issue is taking random elements in the background and using them as backgrounds when I do this. This is the texture corruption that crashed my game at the start of the reprocess I believe.
I will need better replication steps to produce different results. It isn't crashing or skipping if osu! is tabbed out when the process finishes. This could be fixed on the test build or maybe some players just have graphics cards that have worse handling of texture corruption than mine does and so crash more easily.
Edit: I think I know what causes the corruption. Testing
Edit: I'm pretty sure this is what is causing the crashing for people. When a map is loaded while osu! is minimized, it will show a random background object as the background. Minimizing and expanding the game will choose a new object to be the background. You can do this until osu! tries to load something that crashes the game with the error message I posted.
I also got the B rank as a background.
