Dragon Player fails to Show Video When KDE4 Desktop Effects are Enabled

[Shaved Wookie]

Binary package hint: dragonplayer

What I Expected:
Video plays back the same (working) whether using Desktop Effects or not.

What I'm Getting:
Playing video with desktop effects turned off works fine. Turning desktop effects on though causes video to flicker wide black horizontal bars bars constantly (looks just like the flicker when you see a TV screen on live television from being out of synch).

I get this even if I have "Desktop Effects Enabled" checked, but no actual desktop effects turned on (in the "All Effects" tab / the three checkboxes *below* "Desktop Effect Enabled")

This problem also occurs on VLC unless the X11 video output module is selected (although that drops frame rate to about 10 fps @ fullscreen)

Hardware:
ATI HD4860 (running fglrx 8.9)
Intel CPU
Samsung 216BW LCD monitor

Software:
Dragonplayer 4:4.1.1-0ubuntu1~hardy1~ppa1 (2.0.1-0ubuntu2 0)
FGLRX 8.9 (all default in xorg.conf except 'driver "fglrx" ')
KDE 4.1.1 (from PPA packages)
Kubuntu 8.04.1

The dragonplayer source package contains an old version of Dragon Player. Dragon Player lives in kdemultimedia from KDE 4.1 onwards.

Same problem here.
Video playback in VLC flickers badly when Desktop Effects are turned on.

ATI Radeon HD 4870
Intel Q9550 CPU
Kubuntu 8.10

Meanwhile I'm using the Toggle-Compositing Plasmoid http://kde-look.org/content/show.php?content=78299 to disable Desktop Effects before watching video files.

Same problem on Kubuntu Intrepid i386 and Dragon Player and VLC player, ATI Radeon 9550 and enablde Desktop Effects. After some seconds video hides and shows the black screen.
When I enable "Wooby windows" I can see the video in VLC (across black screens) when I moving window with mouse, but when I stop moving window - video goes to always black.
When I disable Desktop Effects, video shows normally.
My xorg.conf:

Section "Screen"
 Identifier "Default Screen"
 DefaultDepth 24
EndSection

Section "Module"
 Load "glx"
# Disable "dri2"
EndSection

Section "Device"
 Identifier "Default Device"
 Driver "fglrx"
 Option "VideoOverlay" "on"
 Option "OpenGLOverlay" "on"
EndSection

Invalidating task for old dragonplayer source package.

Also this seems to be a issue specific to the fglrx drivers.

Confirmed in DragonPlayer and VLC. In VLC, at least I can switch to X11 video, which seems slower, but does not flicker. Using Cheese for picture taking or video capture flickers too, to the point that it's virtually unusable.

Confirmed that I'm using fglrx, too. =/

Hi shavedwookie,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

Hey Jonathan,

I can't actually test this at the moment as there seems to be another bug
preventing me from using desktop effects at all. I'm fine with this being
closed, although I'm happy to post my xorg details here when I can actually
test to see if this bug still exists or not.
