I've had real problems with the display stack once in the last maybe 10 years. And that was simply a case of the software support for Ivy Bridge not being released far enough before the hardware, and thus not supported out of the box on the latest stable release of anything at the time. (Of course our criteria for working might be different -- I care about stuff showing up on my monitor and X not crashing. Couldn't care less about kernel modesetting). In contrast, audio tends to randomly completely break after every other update. Most recent major breakage I had: for one whole Fedora release, the headset mic input would not work in the one app where I need it to work (Skype). Worked fine on the previous and next releases, with the same Skype binary. Minor problems that can be worked around just randomly come and go. Right now one one machine all audio playback will stop working every few days, until pulseaudio is killed. Another computer randomly goes to a mode where all audio playback from Chrome is accelerated by IIRC 7%. Just enough to make you uneasy due to things being off somehow, but not enough to make obvious that there's a problem. This persists until pulseaudio is killed and restarted, of course, which magically fixes things.
