Is anyone else seeing this? After a recent system update, I now see this output from boinc client when my screen saver is on:

... keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvali d MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 keyInvalid MIT-MAGIC-COOKIE-1 ...

This doesn't start immediately, though. If I lock the screen and unlock it, I don't see any of these messages. But, over night, for example, I get as many as 1000 lines worth of this.

I tried rebuilding 7.6.33, but that didn't help and, now that I think about it,
doesn't seem like it would.

It doesn't seem to affect computing, but it's very odd, new, and makes me worried about GPU computing. Since kernel 4.7.5 two weeks ago, I've had several video-related crashes. This may have started with that update, or maybe the next one.
