I'm testing this with Photoshop 24.2.0 on windows 10, geforce rtx 3080. latest drivers on everything.
Often, when switching to another windows application and then back to photoshop the pen loses tilt sensitivity. pressure and everything else works fine.
I use "open documents as tabs turned off" and never use tabs.
I had this problem with wacom, but it was enough to alt+tab back and forth and it would workaround the issue.
I'm now using a huion and its particularly annoying as I have to restart the driver every time this happens to fix it.
could you please test using multiple document windows open (not as tab) as I suspect photoshop has issues realising that the focus is back on one of its windows.
