Good afternoon, since the upgrade to Gnome Shell 44.1 I have to start Firefox twice. The first time I only get a black window but can close it from the top menue. After that it starts normal. When starting from a terminal I get the following message which appears at 2nd successfull attempt as well: ATTENTION: default value of option mesa_glthread overridden by environment. Anyone else experiencingthis and an idea how to get an error message? Thanks Frank
