Every time I use the brush tool in Photoshop CS4, the feather effect on the brush produces this horrible banding instead of a smooth feathering effect. Also when I click once with the brush tool and then shift click on another spot to create a straight line between the two points, the line produced is kind of bumpy - not the straight line CS3 used to produced.
I have no idea why this is happening and wondered if someone else has experience this and has a solution?
I'm using Mac OS 10.5.5.
Really appreciate any help.
