Garbled graphic ("zoomed in effect") in fullscreen 3D applications if other window opens

[Michael]

I've a problem with full screen apps since ages (using ubuntu 14.04 and 16.04 64 bit and gnome flashback+compiz). they are liked "zoomed in", so I see only 75% if there is other window layered over it (e.g.skype messages or apport)...

If I disable unredirect_fullscreen_windows completly fullscreen windows are always distorted in this way. I both tried the original xorg drivers and the ones from http://ppa.launchpad.net/oibaf/graphics-drivers/ubuntu . And also the mainline kernel.

Did this issue start happening after an update/upgrade? Was there a kernel version where you were not having this particular problem? This will help determine if the problem you are seeing is the result of a regression, and when this regression was introduced. If this is a regression, we can perform a kernel bisect to identify the commit that introduced the problem.

On a Lenovo x201s and x61t with Intel integrated graphics (i7 first gen & x3100) it was since at least the release of 14.04 (which was a update series since 7.10 or so), on the Toshiba z20t it was a fresh installation.
