drawFrame/drawRFrame draws vertical lines in wrong position

[SaKiEQ]

I am using Ucglib_ILI9163_18x128x128_HWSPI tft(__DC, __CS), which works perfectly fine in terms of initialization and communication. The display is rotated 180 with tft.setRotate180(); .

When drawing any frame the vertical sides become detached and shifted/drawn in the wrong position (tft.drawFrame(2,100, 40,20)). Now the same does not happen without setRotate, ergo there must be a problem with rotating the screen and certain draw functions ?
