i've been very happily working with 2 24" screens hooked up via a Dell D1000 doc, using the february 3rd drivers on OS X 10.12.3. on a 2012 macbook pro (non-retina)
upgraded to 10.12.4 the other day, which introduced issues that make working with this setup impossible.
issues:
- scrambled popups & other screen elements
- slow performance; dragging windows, doc magnification
The scrabled screen elements are the real problem; f.i. an 'open file' window is completely scrambled, not usable whatsoever, moving the window to the onboard screen resolves the issue.
Also, dragging elements in an application i use (Axure RP) scrambles the elements, and brings the system almost to a halt.
Tried de- and reinstalling the drivers, which at first seemed to resolve the problem, but it has since returned. Perhaps a cold boot/ restart solved it temporarily, and disconnecting/reconnecting with the dock causes the problem to reappear? (this happens several times a day, on 10.12.3 without issues)
i'll update this post with a screenshot.
Is there any info on an upcomming driver update that might resolve this issue? other ideas?
