Attachment: screenshot of the issue

I recently got a new laptop with 4K display and quite often am getting artifacting when restoring Firefox from a minimized state, almost like something being discarded. Sometimes it's all-white, other times it's a mix of white and black. Resizing the window to force an invalidation makes everything reappear. With HiDPI screens becoming more prevalent, I'm worried that issues like these are going to become more commonplace.

To be clear, the only alterations to the attached screenshot was the blurring of the tab titles. The rest is exactly as it appears when the bug occurs.

I'm optimistically going to call this a dupe of bug 1234049.
