I confirmed this happens on caroline.
There is black thin stripe flash beneath the system tray (as if it's a part of drop shadow of it) when the mouse cursor gets into and gets out of the status area.

This happens from 6442a850. I confirmed this issue not reproduce when the change is reverse-patched.

Moving to RBS.

It's now getting risky to keep merging changes into  M-70. This is a regression but I think it's okay to punt the fix for M-71, I'm still not quite sure what's happening, and I'm trying to fix some more visible issues before it's too late to merge anything into M70.
Actually I suspect this may be fixed by CL 1227813.

Blur should have been disabled in this scenario, so this shouldn't happen anymore. Please reopen if you still see this, thanks!
