> I am seeing this issue on emacs head. The text randomly flips vertically. Very hard to reproduce. But if you open a very long C/C++ file like https://github.com/KhronosGroup/Vulkan-Headers/blob/master/include/vulkan/vulkan_core.h <https://github.com/KhronosGroup/Vulkan-Headers/blob/master/include/vulkan/vulkan_core.h> and keep moving around the buffer, cut 100ish lines and paste in another location and then move around again. You might hit the issue.

Wow!  That's got to be some weird problem with you video driver or the
display hardware.  Emacs never does anything like that.
