I've updated the packages from the mentioned ppa. Additional to the border issue I get now quit frequently character distortions (cf. the second "(II)"- line in the screenshot of the terminal window) in different programs.
Please note (cf. comment #31), that using a compositor or not does not seem to have any influence anymore. In both cases I get the striped border and now the character distortion; i.e. disabling the compositor isn't a valid workaround anymore.
