P: Right clicking in canvas opens the brush panel and closes it immediately (wintab)

You're welcome, hopefully this can be fixed soon. The right click also doesn't work in the layers panel btw. If I remember correctly, the right click was registering as left click in the layer panel.

I rolled back to 21.2.1.

Ok, thanks Rinthe.  That info helps.  What version did you roll back to?

I can't reproduce the problem now because I've rolled back. Title should have been WindowsInk, that was a mistake. I'm not sure if this only happens with windowsink or not though.

I have a logitech g pro mouse and have the g hub software installed. no gsync monitors.

Oh, your title says (wintab).  Does this only happen with WinTab and not happen with Win Ink, i.e. with PSUserConfig (UseSystemStylus 0) disabled?

Just to be clear, I'm not trying to blame other apps and I agree this is a new issue with the latest update; a bug we are looking at and trying to fix but we can't reproduce it.  That's the problem. There are several users who are experiencing this and we're trying to figure out what the root cause is.  

Do you by chance have a gaming mouse with related mouse software with it set to a high polling rate and/or GSync GPU+Monitor?

I use photoshop everyday professionally. Nothing new was added to my workflow. Problem only started happening AFTER the update. never had it before.

apps running:
Photoshop
Bridge
Chrome
Spotify

I had to roll back to older version because the new one was unusable. Rolling back version also fixed this issue. So it's the new update that broke it.

@Rinthe what other apps are running at the same time?  We suspect another app may be interrupting a PS tracker.  We need to figure out what app(s) those are and prevent that. Suspects are: OBS and zoom.  

I had this problem around 9 years ago... I'm trying to remember how I fixed this

bump.
