Original GitHub issue: https://github.com/debauchee/barrier/issues/1024

Describe the bug
Barrier puts QSystemTrayIcon::isSystemTrayAvailable() in a loop waiting for 10 seconds, this is a large amount of time to wait for a system which doesn't have a system tray. ( d4382b9b80/src/gui/src/main.cpp (L129) )

Furthermore the Qt docs state that "If the system tray is currently unavailable but becomes available later, QSystemTrayIcon will automatically add an entry in the system tray if it is visible." https://doc.qt.io/qt-5/qsystemtrayicon.html#isSystemTrayAvailable

So it appears that this wait isn't required, as if the system tray becomes available later Qt will automatically show it.

To Reproduce

Steps to reproduce the behavior:

Have a Desktop Shell without a system tray
Launch Barrier
Notice you have to wait a long time for Barrier to start

Expected behavior
At step 3 I expected Barrier to instantly.

Desktop (please complete the following information):

OS: Ubuntu 20.04
Barrier version: 2.3.3

@ahayzen any chance you can submit a PR for this? I'm experiencing this as well and can try to test a fix

@curiousercreative I've created a pull request here https://github.com/debauchee/barrier/pull/1084 which changes how the waiting works, which should ensure good UX in the majority of cases. Feel free to test it :-)
