For what little help I can contribute, I use a Hunion tablet on PC, never had this issue on any version, the issue might be Mac or driver related for ThomasJohan?   Just a thought.

Nope, it's not about driver. I have same issue with Kamvas Pro 24 on Windows 10 - it works perfectly fine in V4, but it's a mess in 2021(except 2021.18). WinTab, no strokes(it worked in 2021.18 and works in V4), WindowsInk/TabletPC, strokes/pressure are working, but with lag on very beginning of every stroke... well, whole ui have this lag, viewport or left side tool panel scrolling suffer from this issue. That's issue is clearly on 3D-Coat side.

I really want to fix the lag issue, but can't reproduce it. So I need some help to understand what changes caused it. 

1) There are 3 links- 17, 18 and 19. Is it right that 17 lags, 18 not lags and 19 lags again?

2) Does it lag over the simplest scene - PPP, default cube, draw strokes of radius 0.05 over one side. Does it depend on radius? Does it depend on Wintab/TabletPC? In which version?

Thanks for your patience and reporting.

- Fixed the lag during the painting/sculpting. This lag is really tricky, was happening sometimes, not regularly, so it was really hard to reproduce and fix. On my side painting/sculpting become much much more responsive. I need to understand how it influenced the sculpt/paint speed on your side.

Please make the fullscreen video, how the lag looks, what tools and settings used. Could be good to show the window Windows->FPS_Monitor
