*MOD Note: The following post is in reference to Insider/Developer builds of Windows 11, these are not recommended for regular usage*
With the December 7 Windows 11 update (KB5021866) much of Start11 is broken. Cannot resize task bar, colors not responsive, many options not available.
It would be normal and expected if you have been upgraded to the 'new' taskbar to no longer have the options to control blur, transparency and colour on the taskbar. This is one of the risks of using unsupported builds of Windows. Start11 should be indicating they are not supported on your version of Windows at this time.
The issue with resizing the taskbar seems to be new but again limited to insider builds.
The new taskbar is still very much in development by Microsoft which is why we have not extended full support to it at this time. It still may get scrapped as it did earlier in the year.
