This is related to the introduction of the Qt bearer plugins.

Upstream Qt bug:
https://bugreports.qt.io/browse/QTBUG-40332

I'll have to remove this feature from Qt entirely.

The Qt bug has been closed by changing the plugin source code, but it was still a problem even without any plugins present:

@TzZek test this one: https://files.multimc.org/downloads/mmc-develop-win32.zip
it's with the previous Qt version and shouldn't have the problem.

If you can confirm that it doesn't lag anymore, I'll rebuild stable with this Qt.

This also affects streaming via steam, causing a lag spike every few secs which pauses the display for a moment each time.

Hope its gets fixed, as atm its unplayable via steam stream in current version.

Try the version above. Before running it, remove the plugins\bearer folder. See if that helps.

will do, just double checked by rolling back a version and was ok...will try that dev one now

Ok version above, without bearer folder...nice stable graph ping etc (steam stream f6)
With bearer folder, spike every few secs...
Thankfully dont have to start minecraft to see it with the steam graphs :D
