Surface pro 4 landscape mode cursor offset

[heggety]

Hi I have a Surface pro 4, which runs windows 10 which is all updated and I am attempting to use the surface pen with no clip with Gimp. When in Landscape mode the surface pen works fine with gimp but when the display mode is changed to portrait I get an offset from where the pen cursor is and where the draw mark appears in gimp. I have set the input to screen on the pen, using Gimp 2.10.12. Any suggestions on how to fix this (I have reported the issue to windows)?
