Pretty sure.  I rebooted this morning.

Usually when I'm having trouble, there are at least two D's.
Of course, 'tain't as crawly as it often gets.

I think this qualifies as interesting.  I have rather a lot of it:
Aug 04 17:28:20 localhost.localdomain chromium-browser.desktop[26614]: [26647:26728:0804/172820.614816:ERROR:latency_info.cc(149)] Surface::TakeLatencyInfoFromFrame, LatencyInfo vector size 102 is too big.

I found it with google, but all the entries froze chromium.
