Bug 121936 – Xvidcap + Translucency = Flickering / segfaulting nightmare

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

[Description georgia_tech_swagger 2006-02-06 23:56:48 UTC]

Running xvidcap with translucency enabled results in a video that flickers crazily (perhaps trying to 'gain focus' through the layers of transparency?).   It also segfaults rather easily/frequently... especially with KDE popups such as the Kmenu or the "icon zoom" bit for program icons in a panel.
