--- Comment #39 from Andrew Dunai anderson.dunai@gmail.com --- Wine 1.9.2 @ ArchLinux here, can reproduce this problem - empty browser windows content.
Also wine native error dialog appears when I attempt to switch tabs: "steamwebhelper.exe has stopped working. Sorry for inconveniences". (approximate translation - original error is not in English.)
P. S. Sorry for double posting: using wine bugtracker for the first time.
