I see—it seems the issue is with the pen tablet after all!
Since the camera rotation function, which I had assigned to the pen button to mimic a right-click, worked fine, I got a bit confused.
It’s probably just an incompatibility issue with modifier keys or mouse buttons.
Thank you for checking this out.
This is a bit hard to explain…
When I’m working in Nomad and click on another window with the mouse or pen (i.e., the cursor),
when I return to Nomad, the window itself comes back to Nomad just fine.
However, for about 30 seconds to 2 minutes, it stops responding to input slightly.
I can’t switch brushes or press the hotbar buttons.
But I can still rotate the camera.
Then, after a while, it seems to “remember” the actions that were paused and frantically catches up at high speed (for example, if you were switching brushes multiple times, it’ll do that), and then it returns to normal.
I think turning off WinTab or Windows Ink might help… but not being able to use pressure sensitivity is a bit of a bummer…
I’m not quite sure if this is caused by Kamvas or by WinTab (or Windows Ink).
Also, this issue might only occur when I switch windows by directly clicking on them with the cursor; I don’t think it happens when I switch carefully using Alt+Tab or similar shortcuts.
Here’s an additional note.
Control Nomad with the pen → Switch to another window with the mouse → Click Nomad with the mouse → No symptoms
Control Nomad with the mouse → Switch to another window with the mouse → Click Nomad with the mouse → No symptoms
Control Nomad with a pen → Switch to another window with the pen → Click Nomad with the pen → Issue occurs
Control Nomad with a mouse → Switch to another window with the pen → Click Nomad with the pen → Issue occurs
Control Nomad with a mouse → Switch to another window with the pen → Click Nomad with the mouse → Issue occurs
It seems like the issue is related to the combination of switching windows and whether the pen is in use.
When the issue occurs, pressing Alt+Tab seems to fix it.
