Bug Description

On an up-to-date ubuntu 16.04.02-amd64 I started seeing some minor display corruption after moving the hard disk containing the ubuntu installation from an older Dell Optiplex (Ivy Bridge i7) to another Optiplex with a Skylake i7-6700 CPU.

I took a photo of the screen corruption which I attached here.

Xorg.0.log lists the used driver as 'intel'.

I am using the stable chrome release, currently at "Version 59.0.3071.115 (Official Build) (64-bit)".

The corruption (display artefacts) usually show up when hovering the mouse over the 'back/forward' browser buttons, or after navigating backwards/forwards and waiting a couple of seconds. Sometimes they go away leaving a normal browser window, other times the artefacts remain as shown in the attached photo.

Browser flags I have tried include combinations of:

--wm-window-animations-disabled
--disable-gpu-driver-bug-workarounds
--enable-native-gpu-memory-buffers

One important detail: I also had an AMD radeon video card plugged in but the display was connected to the integrated VGA port. After removing the radeon card, the artefacts went away.
