Toshiba TruPen on a Toshiba Portégé X20W produces wiggly and shaky lines when using libinput under wayland
Hello, I have an issue with the Toshiba TruPen on a Toshiba Portégé X20W. The Toshiba TruPen is a digitizer pen and the Toshiba Portégé X20W a convertible laptop with a touchscreen. While drawing in Krita and Xournal the lines are wiggly and shaky. This effect is especially present when drawing slowly. Also the position from the pen cursor and the actual pen position do not match, while approaching the touchscreen with the pen. As a result an unwanted line is drawn between these two positions. If i try to paint some small dots, thereby small lines are drawn.
This issue only exists under Gnome Wayland. While using Xorg the digitizer Toshiba TruPen behaves as it should.
