I use Xubuntu on a computer with an Intel 82852/82855GM video card and have a nasty problem with video playback: after some time of playback a video player screen comes just blue, and when I close it my screen is filled with garbage and the system hangs. The workaround I've found is using mplayer with -vo x11 to render it software. I understand (because the same case caused similar problem in Arch I used half a year ago, not just Ubuntu, and the problem never occurs when I use other window managers than XFWM) that this is probably a problem of the combination of My Intel card with XFWM. From this comes the problem - where to submit the bug - to XFCE bug tracker or to Intel one (which I even have no idea where to look for). At the same time I wouldn't like to register in those issue trackers just to use them once. So I am not straight about submitting the bug, but can explain clearly how to reproduce it, which, I believe can itself still be a useful contribution to the community.
So, is there a way to submit a bug I've experienced without complications, for better-qualified specialists to review it and put into corresponding issue trackers themselves if they aren't there yet?
