Original GitHub issue: https://github.com/rivo/tview/issues/377

My team is using tview for a console application and our QA team reported a usability bug. When the window is resized on Windows, the screen flashes. The flashing continues for a short time after the resize is finished. It isn't a huge issue, but it is a little ugly. I captured a gif that shows the flashing. I resized a few times, with some ridiculous resizes just to emphasize the effect, but you can see that it still occurs with a normal resize:

I believe this can be mitigated by adding some throttling to the EventResize handling here. I'll open a PR with a suggested fix, but I'm not very experienced with golang so please go easy on me!
