i have a 24 hd cintiq. when I draw a vertical line, and only vertical, I'm getting random jagged bumps. but when i plug the cintiq into a different computer it works fine. I tried re installing driver but no luck. any ideas??
There are a few things that could also be an issue:
How worn is the nib on your pen?
What is the difference in resolution?
Are you more or less zoomed out on the computer other computer?
Often times a jagged edge can come from some communication in the connection of the tablet to the tablet pen. If you're too zoomed out, the natural shakiness of your hand might cause the program to jitter.
