Writing back to say this is still broken. I did try adjusting the key repeat rate and have kept up on all updates of both photoshop and the system.
I'm hugely dissappointed that something I used to find very useful is now broken and useless.
Please fix this problem ASAP.
I feel your pain, this bug has been around since before mavericks but became much more frequent after mavericks. Ive been posting on both the wacom and adobe forums for months now but so far there is no progress at all.
if im correct you are experiencing this :
the patch notes said lasso tool was supposed to be fixed but mine is still very broken
Yes. That's exactly what's happening.
Hugely dissappointing. I used to find the magnetic lasso tool quite useful.
