We are aware of many issues on MAC OS, but unfortunately we have no developers with this setup to investigate and reproduce the problem.
There are plans for Blender to support Vulkan in addition to OpenGL.

When this is done, many of these problems will likely be solved.

In fact, I have the same problem. If Blender's 3D viewport is assigned to two monitors, switch the monitor and click on the Blender window on one monitor to activate it. The other monitor's blender window will flash and show me,One frame in the window operation in the previous few seconds, as long as it continues to operate normally in another window, the stagnant frame will return to normal and the screen will be refreshed synchronously.

I have the same problem on recent 2.81 build under Windows 10. I use GTX 1660ti on my laptop, all drivers and OS are up to date.

Is this still an issue with latest build? https://builder.blender.org/download/

Hello Richard,
after a brief testing it seems to have been fixed. One would require a long term testing which I am unable to provide for moment.

Thank you all
