I’ve recently started to get the glitches shown in the attached pictures. This started not long after I upgraded my graphics card. However, these only appear in Cubase - every other application (including Windows) is unaffected, leading me to believe the fault lies with Cubase. Both Cubase and the graphics card are up-to-date.
Cubase Artist 8.0.40 build 623,
NVIDIA GeForce GTX 750ti.
