--- Comment #52 from Jay Hilliard jaydhilliard@gmail.com --- I had to do a few things. Added the patch here for the dot problem. Modified slightly to work with wine 1.7.47 (git) Added the patch to fix pressure sensitivity "final patch candidate" from https://bugs.winehq.org/show_bug.cgi?id=18517 Except not the context.c part of that patch which is already committed. That's it. Build the patched wine and when you run photoshop, if you have a tablet with Touch, you will want to set TapTime for the stylus to 0 as noted in a my previous comment. If you don't set TapTime to 0 the stylus response will be so bad/slow it's unusable with the stylus.
There still exists an issue where when I paint multiple strokes quickly, say 5 time, 2 or 3 of the strokes will not have pressure sensitivity applied and they look very different. If you paint slower it works. I think it's something to do with the dot problem not being fixed "correctly" (cache issues between mouse and stylus?) or perhaps initial defaults for x,y,pressure shouldn't be 0xfffff, but rather be 0x0. I don't know. Any help appreciated.
