--- Comment #53 from Jay Hilliard jaydhilliard@gmail.com --- I was able to work around this bug (the dot issue) by patching the evdev package with the debounce patch. The problem went away just like that without disabling the cache as other patches in this bug do, So, debounce is masking the actual issue. It looks like we're getting a double click which causes the dot issue. I also noticed the first button activity (debugging wintab stylus button activity) shows the first packet with a non-zero value has a button value of 0. How can there be pressure with no button? so I wonder if that's causing it. Could multiple mouse devs be passing the click? Anyway, given that it can be fixed by patching evdev with debounce, perhaps we can implement debounce right in wine. The funny part is I have no need for the debounce patch outside of Wine/Photoshop. Linux apps don't seem to have this issue.
