I bought a new pen tablet. A Wacom QHD27" and I've run into the same bug as my companion. (irritating)
Basically when using a drawing program (photoshop/SAI) the pen pressure intermittently stops working for a stroke or two. Example is
"stroke, stroke, STROKE, stroke STROKE...etc".
This was an issue with my Cintiq companion as well but though it was just a defective model, apparently
a lot of others are having the same problem (on Wacom EU forums because Wacom U.S. and doesn't even have one)
and the problem hasn't been pin-pointed yet.
Anyone else have this issue and found a fix? Thanks!
