Even this issue (Windows 11) should be well known meanwhile and it doesn't matter WHERE TrafficMonitor has been positioned on the taskbar: on the left or on the right...

Left

Right

...I wonder why this has never been fixed. TrafficMonitor seems to be "just" an overlay which currently does not reserve it's own full actual space. So whatever comes from Windows, it wins - and you can't read anything from TrafficMonitor. Very frustrating as it limits the usage by a lot. Otherwise this application would be really perfect, especially coming from former NetSpeedMonitor (stopped working with Windows 11).

System details - as up to date as one can be:

Really hope @zhongyang219 is still maintaining this great software, because looking at almost 1.000 open issues (a bunch of them and more can be smashed if only this single taskbar overlapping issue finally gets fixed) and the last release almost one year ago doesn't feel like it is to be honest.
