I solved the problem!
I think it was some kind of incompatibility with my current graphics tablet (Hion HS610).
I uninstalled the drivers and unplugged my Huion, and SpaceDesk worked, with pressure, in photoshop
On my laptop (MX550) it worked! but on my computer (RTX2080 Super) it didn’t work… only in photoshop.. in Microsoft Paint it worked, despite not recognizing pen pressure
Attached is the drive diagnostic file
As you can see in the video, pen pressure works fine on the tablet and supported apps, but it doesn’t work on SpaceDesk
