--- Comment #4 from DenTaKu dentaku@web.de --- Well, the bug report has a date - so "yesterday" is quite exact. I just wanted to note that it just happens without any changes on my side - just updates from Ubuntu and Steam. I already reinstalled steam and used fresh wine prefix but with no success. I will try to redownload the games but they have multiple gigabytes - through slow internet connection. :-(
