Bug Description
My mouse inputs aren't being handled properly by a few but not all applications in Ubuntu 16.04 using the Mate desktop. The problem occurs on my system that has 3 gpus, 5 monitor setup with compiz, accelerated graphics, and xinerama enabled. I'm using the Nvidia 361 drivers. I do not have these problems on my laptop, a single monitor setup with compiz and accelerated graphics enabled.
Applications like the Caja file manager handles all the mouse inputs correctly, but the Dolphin file manager doesn't. In Dolphin, I can mouse click the menu items just fine, but any sub-menu mouse inputs are not registered. Also in Dolphin, none of the mouse inputs are recognized while clicking on any of the files/folders/
Other applications that exhibit this odd mouse behavior are VLC and SMPlayer (see https:/
If you want, I can record my desktop to demonstrate the problem.
So far, you've not listed an application from the MATE desktop as being affected by this issue, in fact you specifically state that Caja (the MATE file manager) work correctly.
I also have no way to reproduce this issue given your exotic hardware configuration :-(
