Hi Sigrid, Check that the toolbox on the left hand isn't too wide for your screen. If it is, you can drag the toolbox to be wider and then resize the Krita window. See: https://docs.krita.org/KritaFAQ#Krita_can.27t_get_maximized The second issue is probably specific to your system. You didn't tell us which version of Krita you use or which version of which operating system, but for instance, certain combinations of Windows 10 updates break the Wacom wintab drivers with Krita 2.9. You can try the 3.0 alpha to see if that works better.
Make sure that the cintiq is set to the right monitor too, that got me a couple of times. I can also recommend trying 3.0.
