parallels desktop 11, multiple monitors/aspect ratios broken

this is something I've noticed for a while. I have a mac pro with 3 monitors and 1 cintiq 24HD. the cintiq is 1920 x 1200 while the monitors are 1920x1080. I've actually tried this with both 1920x1080 and 4k dell monitors which is double that resolution.

all windows apps work great if the cintiq is not plugged in but once I plug it in, the maximize behavior starts mis-behaving.

I start running into issues where the app does not fit the window properly, like the whole app window is offset by some random number of pixels and sticks off the top of the screen.

I also periodically run into situations where the mouse does not line up with the app. as if the guest os is offsetting the mouse position by about half screen to the right.

when I first start using the cintiq, I can get it working for a bit, but once these errors start happening, the only way to fix it is to unplug the cintiq.

 

Hi, please try to update the Parallels Desktop 11 to the latest build and reinstall Parallels Tools.
Let us know the results please.

 

I have the latest parallels, parallels tools, windows, and os-x.
this has also been a problem that has happened on earlier versions of parallels as well. the issue is I dont often work at home with my cintiq so I dont notice it, but when I do need to work with my cintiq, I have these issues.
