Comment 18 for bug 1766076

I can confirm this is a regression between Artful and Bionic.

I downloaded the 4.17-rc3 kernel yesterday afternoon, and it seems to be stable for me.

I'm going to try to make time to bisect which commit contains the fix, which will likely take a couple of weeks. Since the dock is at work I'll be able to test at most one build each evening before I go home, and probably no builds on some nights.
