**System Information**
Windows 10 Home, version 1909, 64-bit
GTX 780, driver 460.89, a fairly recent driver but it was also happening on a much older one
**Blender Version**
Broken: 2.83.0 - 2.83.10 (still broken as of latest 2.92.0 alpha experimental build acbda123ad08)
Worked: 2.82.7
**Short description of error**
Vertices flash when the screen is updating. Only on my desktop using a GTX 780, not my laptop using an i7-1065G7 (Intel Iris Plus)
**Exact steps for others to reproduce the error**
Create an Ico Sphere with subdivisions set to 6. It happens at levels 5 and 7 as well, but not nearly as noticeable. It seems related to a specific vertex count, rather than proportional to the number of vertices.
