My MacBook Pro's screen has had flickering issues since, well, a couple of -current updates ago. By "flickering" I mean the screen going dark for very small units of time. It happens when I load ads in Chromium, when I type in the Chromium address bar, and especially when slackpkg is downloading stuff.
It seems to have a correlation with network activity. However, it does not happen in OS X, so we can eliminate the possibility of a hardware issue.
I've tried using an xorg.conf.d file to set the acceleration method to UXA and to SNA. Neither seems to make a difference.
I've found this bug report, which looks to be relevant. I haven't had a chance to try any of the patches in it yet though.

We've been discussing intel driver issues over here, and had some success rebuilding the intel driver using a different revision. I was seeing something similar on my XPS but it's gone away on the newer driver. Your mileage may vary of course..
Could it be hardware failure? That's the worse flicker to encounter ime
it was a nvidia 6800gt from beginning to end
does it happen in the terminal?
I would still see the flicker if I switched to a virtual console when it was happening in X. I didn't have a chance to test from runlevel 3 (there were no -current updates to download since the 6th), but I will when I pull the update that -current got today.
I find it very unlikely that it would be hardware failure, as it started happening after a slackpkg update and it does not happen in OS X. I am starting to wonder if it what broke it might have been the 4.4.6 kernel and/or its wifi driver though. I've seen google hits about broadcom drivers causing similar symptoms on very similar machines.
