Hello @Callum, thanks for a prompt response! 😇
"If you try using the pressure functionality without a custom pressure curve set does this issue still occur?"
In my case, the pen pressure graph was by default set to curve number 3. I mean the one next to the pink "h". I wasn't satisfied with the way it worked. That's why I decided to customize the curve and see whether it helps (it didn't).
"If you change the tablet input method to Windows INK does this issue still occur? Do you have any custom Windows INK settings that may be conflicting with the apps?"
Yes, unfortunately, this issue still occurs after changing the tablet input method to Windows INK. I've never changed anything in the Windows INK tab, so I assume that everything there should be fine.
I'm attaching screenshots so it's easier to see what happens. The Huion app looks a little out-of-date because some days ago I tried to install the v13 drivers. I've heard that installing the older ones may help. However, my pen pressure issue occurs with every version of Huion drivers.
Do you think this issue arise from my device? Or maybe from the brush I'm using?
I hope that everything is clear, many thanks for your support!
