No.17968 Tafoid Administrator Sep 11, 2020, 19:18	Ahh yes, correct. Unless I zoom in on the snapshot I can't even notice it on my monitor. This is among many machines which have darker or lighter sections of blocked off background and is true to arcade. Other examples: 01683 02062 05417 06116 06508 .. and I'm sure many more I'm not seeing at the moment. Resolving
