zooming desktop shows uninitialized memory I found the desktop zoom (alt+scrollwheel) feature by accident, but happen to like it. I also found a minor bug in the desktop rendering using multimonitor. I have two monitors, one on top of the other. A wider monitor is positioned over a narrower one. when I zoom in to the area to the bottom right of the wider monitor. The area where the wider monitor overhangs the narrow one, a rainbow pattern is displayed. Please see the linked screenshot. http://imgbin.org/index.php?page=image&id=18182 I am running xubuntu 14.04 64 bit. xfwm4 --version This is xfwm4 version 4.11.1 (revision 2b800f4) for Xfce 4.10 Released under the terms of the GNU General Public License.

I did more testing and found that taking a screenshot produces the same pattern even when not zoomed. I'm using the nouveau driver with an nvidea graphics card on a laptop: $ dmesg | grep NV [ 0.000000] BIOS-e820: [mem 0x00000000cf67f000-0x00000000cf76efff] ACPI NVS [ 0.217167] PM: Registering ACPI NVS region [mem 0xcf67f000-0xcf76efff] (983040 bytes) [ 1.776036] nouveau [ DEVICE][0000:01:00.0] Chipset: GT218 (NVA8) [ 1.776038] nouveau [ DEVICE][0000:01:00.0] Family : NV50 [ 24.769072] input: HDA NVidia HDMI/DP,pcm=9 as /devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input20 [ 24.769171] input: HDA NVidia HDMI/DP,pcm=8 as /devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input19 [ 24.769229] input: HDA NVidia HDMI/DP,pcm=7 as /devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input18 [ 24.769366] input: HDA NVidia HDMI/DP,pcm=3 as /devices/pci0000:00/0000:00:01.0/0000:01:00.1/sound/card1/input17
This is not an Xfce problem. Please report it at bugs.freedesktop.org.
