--- Comment #36 from Dmitry Kazakov <dimul...@gmail.com> --- Hm... I still can reproduce it only with Instant Preview on. But no slowdown is visible in Instant Preview mode off. And looking at the video it looks like the problem on the reporter's computer is not related to IP, because it also visible on 3000%+ zooms, which is when IP is disabled. I have a feeling that it is XP-PEN related. Here I use Wacom for testing. -- You are receiving this mail because: You are watching all bug changes.
