Short description of error
When using a Huion Pen Monitor and Windows Ink, the first few seconds of pen tool touch do not respond. The touch eventually responds, and there is no pen lag afterwards. Just the initial touchdown of all strokes.
All "touch and hold" features disabled. Pen works correctly in other Pen apps like Leonardo, so this is not an OS/pen issue. Huion pen uses Windows tablet generic driver, no special driver installed.
Exact steps for others to reproduce the error
I think this is specific to generic pens on non-wacom tablet monitors. Would probably repro just by doing any free-hand pen drawing with the hardware configuration.
