Enhanced Zoom not working with dual displays

[zippidy_josh]

Enhanced Zoom used to work fine with my dual displays. Then I upgraded Ubuntu and it stopped working. When I try the mouse control to active it, the mouse disappears and no zooming happens.

System info:
- Ubuntu 17.04 (X 1.19.3, Compiz 0.9.13.1)
- Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller
- Kernel driver is i915 (linux 4.10.0-22-generic)

From 'glxinfo' there is:
  Extended renderer info (GLX_MESA_query_renderer):
    Vendor: Intel Open Source Technology Center (0x8086)
    Device: Mesa DRI Intel(R) Haswell Desktop (0x412)
    Version: 17.0.3
    Accelerated: yes
    Video memory: 1536MB
    Unified memory: yes
    Preferred profile: core (0x1)
    Max core profile version: 4.2
    Max compat profile version: 3.0
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.1

Thanks for any suggestions. I looked to post in the forum, but it's locked.

Hello,

I cannot confirm the issue you described.

Do you have the same images on the two screen ? Do you have tried with the Mate desktop ? I've never try Unity but on my Compiz 2:0.9.12.2 it works if the two screen have not the same images.

You have to zoom on the first screen and after that move your mouse and zoom in the second screen. You can have two different zoom level on each screen.

Best regards.
