Installed the following version on Debian 11 ‘bullseye’:

This version looks have flaws with mouse support. For instance, unable to change fore- and background colors in Calc just with a mouse click, a color left unchanged. Another example - unable to change a selected text color with another one selected from a drop-down list by mouse. Only keyboard moving with following ‘Enter’ are working for that.
