I forgot to mention, I use 64bits Release 28. It is fine in the main menu. When I start a new game, it crash after it is 100% loading.   If you can provide a pre-built version, I can help test it.   By the way, I test the latest AMD driver: Adrenalin 26.5.2 with 64bits Release 28. The results of Alt+Tab issue and crash issue are the same as Adrenalin 25.8.1. (Release 28 Adrenalin 26.5.2)crashlog.dmp (Release 28 Adrenalin 26.5.2)crashlog.txt

can you give me an example?  and where do you get the warning?

If I do a mod version that is not a certain way, it gives a warning, I just wanted to disable that, but I don't know where that would be

I'm not really fond of "customizations" either, lots of code for little value. Having a single toggle for two UIs, the current "CRT" optimized one and a new one focusing on modern format 1080p and 16:9 supporting also 21:9 and whatever insanely wide monitors exist. The "LED" version would scale well on modern resolutions, be it 720p, 1080p, 1440p or even 2160p. It could also incorporate many of the suggested changes, I can't say I absolutely love the mock ups but they are much much better than what we currently have. Once the "LED" one is polished we can consider dropping the "CRT" one at some point.
