Package: xfwm4 Dear Maintainer, I have the latest official debian stable release installed on three different machines with different graphic cards (intel,nvidia) and XFCE as the default DE through the installer. All of them have the same issue: Horizontal lines "tearing" when moving windows or watching video. I try to enable/disable xfwm's compositor but nothing change. Installing and using other compositor such as compton, solves the problem (Only some performance issues remain). So i suppose this is a xfwm4 bug? -- System Information: Debian Release: 7.7 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 3.2.0-4-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages xfwm4 depends on: ii libc6 2.19-13 ii libdbus-glib-1-2 0.100.2-1 ii libgdk-pixbuf2.0-0 2.26.1-1 ii libglib2.0-0 2.33.12+really2.32.4-5 ii libgtk2.0-0 2.24.10-2 ii libpango1.0-0 1.30.0-1 ii libstartup-notification0 0.12-1 ii libwnck22 2.30.7-1 ii libx11-6 2:1.5.0-1+deb7u1 ii libxcomposite1 1:0.4.3-2 ii libxdamage1 1:1.1.3-2 ii libxext6 2:1.3.1-2+deb7u1 ii libxfce4ui-1-0 4.8.1-1 ii libxfce4util4 4.8.2-1 ii libxfconf-0-2 4.8.1-1 ii libxfixes3 1:5.0-4+deb7u1 ii libxrandr2 2:1.3.2-2+deb7u1 ii libxrender1 1:0.9.7-1+deb7u1 Versions of packages xfwm4 recommends: ii librsvg2-common 2.36.1-2 ii xfwm4-themes 4.6.0-3 Versions of packages xfwm4 suggests: ii xfce4 4.8.0.3 -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
