There are some relevant skl watermark > fixes. 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</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
