Using windhack but there are no modules active. No other apps.
Also: I tried on other 2 PCs -> one was working as expected, but one had the same bug as me... So, I think there should be something? It's not isolated
If Windhawk is installed, note that it may influence taskbar behavior even when no modules are enabled. To rule it out, uninstall the application, reboot the system, and retest.
For the second PC experiencing the same problem, please check if Windhawk is installed there as well.
