Does anybody know about any setup option (gnome/gtk/radeon driver) that may cause corruptions as shown in this bug: https://bugzilla.redhat.com/show_bug.cgi?id=679579 PNG: https://bugzilla.redhat.com/attachment.cgi?id=480275 I tried to use various video modes, color depths etc, but there is no difference. Thanks for any hint. Adam Pribyl
