I couldn’t catch a single stutter in the videos while I was making inputs and my screen recorder FPS count didn’t show any FPS drops (which it does when stutters happen in the games i play) I tested this yesterday after I ran out of replies - I ran movies and youtube videos on one half of the screen and stared at them while I applied inputs in Krita on the other half of the screen.
The lag occurs only on the Krita canvas and nowhere else on the PC. I would have recorded with my phone as it is not affected with lag. Of course the lag will not be registered due to the sync of lag. The most curious thing about this case is the fact that the computer with lag is the one recording its own lag. I tried using the software on my laptop with the following specs and the stutter is even longer there: This is exactly how the stabilizer should work without the stutter.
