glx-dock openGL 2.2.0-2
archlinux
openbox+xcompmgr
no DE
Hi guys, I just installed new version of glxdock, and the problem is that when dock hide/unhide a white trapezium is shown. Sorry but I had not be able to make a screenshot, so I made a video.(Don't care about framerate, it's the default setting of xvidcap, in real use dock work smoothly)

Hi, could you confirm those informations please ?
Graphic card : Ati x300 (radeon driver)
video is the best to show such bug  , you can even use the drop to share applet to send it to videobin and use [ video=videobin]+ABCDEFG[ /video] (without spaces) when you have such url : http://videobin.org/+ABCDEFG.html |

Yes, I confirm my video configuration. Thanks for the info, i didn't know videobin, and now i'll give a chance to dropToShare applet too. 
Unfortunately with this applet I have the same problem that I still have with ShowDestop applet http://www.glx-dock.org/bg_topic.php?t=3574 |

Hi,
most probably a bug in the graphic drivers
Are there any other problems, like some applets being invisible (dustbin, clock or any other) ? |

Ok. To make a little debug I activated many other applets.
visible:
every custom launchers
showdesktop
folders
invisible:
shortcuts
switcher
dustbin
quickbrowser
dnd2toshare
stack
applications menu
If you want me trying someone in particular, let me now.
TX to both of you for the attention. |

Hello Chris,
I think the best solution is to use a newer version of Mesa/xorg. So it can be interesting to use a newer version of Ubuntu  |

I'm on archlinux, that's rolling release, and the problems are the same.
glxinfo | grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
OpenGL version string: 1.5 Mesa 7.8.2 |

Ok but your glx version is a bit old but it's maybe due to your video card |

ok thanks for the details, now it's sure it's a problem in the drivers
Seems Mesa drivers are still far from being usable  I think the only solution is to give up on the opengl until they are updated, and run the dock with the cairo backend (you'll just loose the fancy effects)
meanwhile, reporting this bug to the Mesa devs would be helpful, thanks ! |

yes, and he said Although I've had missing icons for awhile
so the drivers are buggy from the beginning.
it just happens that we now uses opengl for the hiding animation, which was not the case before, so you have more troubles with those drivers.
cairo-dock -c should solve the problem with a minimal drawback. |

So, do you think whole mesa project it's buggy from its root, and doesn't implement well OpenGL api?
OT
2 questions from an ignorant, if you have better things to do, simply don't answer. 
cairo backend ain't based on OpenGL? Why with cairo these problems don't appear?
why did you switched to a pure OpenGL backend? (I tried to write a little pygtk shutdown program, and without using cairo it'is foolish just to draw a rounded-border window  ) which are the advantages? |

mesa is a great project for drivers, but most of free 3D video drivers are far from being complete / debugged
the dock has 2 different rendering modes, but the opengl is newer and wasn't complete, so some animations were still rendered with cairo backend (for example, I saw that graphs are still done with cairo)
opengl use 3D hardware acceleration, so it's faster and lighter for those with good video drivers. But don't be afraid, the cairo backend won't dissapear |

fortunately not
but they lack of support for many opengl functions that we are using (especially, and that's the main problem, when a transparent window is using opengl; for normal windows, like games, the support is correct).
cairo = safe because uses CPU and not graphic card, runs everywhere, use it without hesitation if you experience any problem.
opengl = fast because uses graphic card, 3D and shiny effects, but needs proper drivers (nVidia, recent ATI, most of Intel). |

Ok, so, cairo is a graphic library ALTERNATIVE to OpenGL? I thought it was another "layer" built on those library...my fault  |

Hi guys, is everything fine? I want just to say that now, since last mesa upgdate I can use glx-dock in opengl mode fully functional. I think this is due to the introduction of Gallium3D library in this drivers. Bye guy, and thanls again for the software
glxinfo | grep version
server glx version string: 1.4
client glx version string: 1.4
GLX version: 1.4
