I've recently upgraded my devel desktop to Ubuntu bionic (~18.04) which comes with Mesa 18.0.0. Now I'm seeing some corruption with Firefox, like the white blobs on this video:

I also get it sometimes when playing youtube videos, and then the blobs are more colorful..

I didn't have this with 17.2.8 before upgrade. Also, I haven't seen this on my KBL laptop, while this desktop is SKL.. both running same versions of everything.

You need to disable gpu rendering for firefox

layers.acceleration.force-enabled;false

If you have a web page that reproduces this 100% of the time, then we can bisect.  As it stands, this is a dup of bug 104890, which after investigation appears to be due to a FF context synchronization bug.

yes, I had that on.. after disabling it I haven't seen the corruption anymore
