This seems to affect Firefox, maybe others as well but that's what I use it with. I have a particular Firefox profile running some server interfaces that I usually keep in the system tray. With 9.9 the trigger to minimize the window worked fine and I got one icon, but in 10.0 it is adding an extra duplicate non-clickable icon each time I minimize the window. I can exit DisplayFusion to remove the excess icons.

For some reason, when I try and record a video with SnagIt, the Firefox window will not minimize to the system tray at all. It seems to be interfering with DisplayFusion somehow. I have attached an image of the trigger details instead along with before and after system tray images.

From a fresh restart of DisplayFusion where Firefox is not minimized, if I minimize the window once I get two icons appearing. One is clickable and restores the window, the other is not clickable. Minimizing a second time creates a second unclickable icon to make three in total.

Unfortunately not, just tried it. Firefox minimizing to system tray still generates an extra unclickable item every time the trigger is called.

I currently have Firefox 111.0, 64-bit. This is on Windows 10 21H2.

So far it looks to be fixed in beta 3, thanks. If it re-occurs I will post back.
