Description

Assuming:

local ov = mp.create_osd_overlay('ass-events')

Updating the ov.data and calling ov:update() during pause event on windows will be ignored and not update the overlay.

Reproduction steps

I've isolated the bug into this script: https://0x0.st/i7mf.lua

It renders a pause indicator when playback is paused.

1. install the script
2. open any video on windows
3. spam pause

Most of the time, the indicator won't be rendered when video is paused.

In my tests, at least 40ms delay is needed before calling ov:update() for it to render consistently, but that might differ for others.
