Hi Christian,
I could test this now and can confirm there is an issue with mdlView_getViewRectangle and the Ribbon menu.
From the test results the y- value of the upper left corner (origin) is the same with Ribbon minimized or maximized - that´s not correct.
The y-value of the lower right corner varies, although it should be the same - that´s not correct
I will follow up and file a defect to address this issue.
Best regards,
Artur
