Adrenalin 26.1.1 vs 26.2.1 - VERY strange behavior
VERY strange behavior

26.1.1 my 184Hz Back Porch Horizontal = 1
26.2.1 my 184Hz Back Porch Horizontal = 43 ( had to increase because artifacts jagged picture )

HOWEVER

my 284Hz Back Porch Horizontal = 1 remains working

I don't know why that would happen. Usually multiples of 8 for horizontal values are most compatible, but this seems like it wants a minimum blanking of 76.

found the problem, and it actually happens in previous driver versions to, only difference i wasn't using the script
which imports CRU profile, restarts driver and then auto sets 184Hz BEFORE i change to 12bit in adrenaline
