Bug description

File Upload-Speed reduces to approx 1/10th of the Speed when the Tray-Window is opened. As soon as the Tray-Window is closed or the Settings-Page (Main Window) is opened, the Upload-Speed speeds up to maximum network bandwith.

Steps to reproduce

1. Create a big file for Upload (I've used fsutil)
2. Open Task Manager to track the network load
3. as the upload is starting -> click on the Nextcloud tray icon to open the tray window -> upload-speed is decreasing

Expected behavior

Consistant Upload-Speed

@mabeck007 so you may close this bug and maybe add valuable details to #4918
There is also a possible fix provided in #4918 (comment) by disabling the syncing icon animation.
