Additional Information

To repro launch following app:

flash.zip

It's not clearly visible on every mac machine but it's quite severe on some of them.
Issue started to show up after this chromium change landed: https://chromium-review.googlesource.com/c/chromium/src/+/6064185
With this change native widget (content view of the window) is hidden on a call to BrowserWindow.hide. It wasn't hidden before so its visibile state was set to visible even when window it belongs to was hidden.
