New since 2016-05-23?  the watermark error message went away, the flashing
black screen did not.  I tried a later nightly and the problem got 10x (not
exaggerating) worse and more frequent.  I notice that sometimes after it
flashes black, my monitor will report that the gpu is sending it an
unsupported/non-optimal refresh rate that isn't exactly the 60hz it expects.  A
reboot (even a soft reboot) fixes it.

I'll try the current nightly again now but I suspect the watermark fixes you
are referring to have already been tested
