I ran into the same issue - don't know what the policy is, reply to this 9 month old thread or open a new issue? Anyways…
Some CAD applications rely on right click + drag for either camera rotation or panning. This obviously doesn't work with mouse gestures and while you're able to disable them on a per-app basis, it doesn't stop BTT from intercepting the input, it only stops the gesture from being triggered.
Right click + drag with gestures disabled for that app doesn't seem to recognize that the right mouse button is still pressed, it only "sends" a single click to the app.
The only workaround seems to be to either disable BTT completely for that specific app or turn off mouse gestures globally.
I don't know if it's a limitation or an oversight?
