Submitter: Andy Bailey Email: [email protected] minimig-mist release: 1.1 (minimig-mist-1_1_20150910.rbf) firmware version: 150910 kickstart version: 40.68 chipRAM: 2MB fastRAM: 24MB slowRAM: 0 game / demo: Workbench main screen, also noticed issues when running Ork (various versions tested) description of the problem: Graphical offset when using ECS or AGA modes as follows. ECS - when booting Workbench I load AWS (Amiga WorkStation) during bootup. In ECS mode there is a vertical bar of colour 1 pixel wide on the left hand side while AWS is displayed (the bar is the same colour as the AWS background). Similarly at the WB screen there is a single bar at the left had side where the colours are wrong. This disappears when running a game (I've used Ork as an example) AGA - No issues with AWS, and Workbech is also fine. Ork however shows a line of colour on the right hand side during the Intro screen. I assume that the intro is dual playfield, and it looks like one playfield is offset by one pixel - the colours within the line change, and I think it's the right most line of the rear playfield showing through.

I can provide pictures if necessary.

Hi, thanks for the bug report!

I'm aware of this problem - the bitplanes can sometimes be aligned one pixel to the right or left too far, it comes from the subtle difference how ECS/OCS and AGA handle bitplane output shifting. I'll have to rethink how the bitplane shifters are implemented.
