GPU scaling mode "Preserve aspect ratio" stops working permanently after driver crash, happens not the first time and not on every crash (driver reinstall, official amd cleanup utility, clean install option from driver does not work). As far as I remember this bug occurs in any relive version of driver (wasn't happening before relive appeared). Last time it happened I reverted back with full system backup, now it happens again and I don't have a fresh one.
-Scaling modes - Full panel option and Center are working with GPU scaling switch in any position.
-Preserve aspect ratio mode works as Full panel only.
-Changing switch does GPU restart restart as usual (screen goes black).
-After rebooting, scaling mode is set to Full panel regardless of previously selected setting (unlike before).
Most likely this problem is caused by broken registry keys after crash, and is not fixable by official troubleshooting methods.
