I have upgraded both my desktop on my laptop (specs below) to Kubuntu 12.04, and along with it came the 2.0.0.1 version of Glx-Dock. I am experiencing a bug that happens on my laptop, but not my desktop. I have the dock on the left side of the screen, set to auto-hide and to appear when hitting a 200 x 2 zone. If I keep my mouse at the very left edge of the screen while I move it up and down the dock, or if I continue to press to the left edge of the screen, the dock will continuously disappear and reappear. I have created a YouTube video so you can see this bug in action: http://youtu.be/7rZrldD9hZU

This bug did not occur with the version of Glx-Dock in Oneiric. I'm not sure if this has anything to do with it, but my desktop supports OpenGL 2, but my laptop only supports OpenGL 1, if I'm not mistaken. Anyway, here are some other notes on this bug:
    • The bug occurs whether the callback mode is the screen border, "where the dock is", or "hit a zone".
    • The bug occurs when the dock is on the top or left edge of the screen, but *not* on the bottom or right.
    • The bug occurs whether using Cairo-Dock or Glx-Dock.
    • The bug occurs whether desktop effects are enabled or disabled.
    • I tried deleting my ~/.config/cairo-dock folder, but the bug still persists.

Well, I just discovered that the problem does *not* happen if I plug a mouse into my laptop and use that. It only happens with the touchpad.

One more thing. On both systems, I can reproduce what I believe is a related symptom of this same bug even when using a mouse. Here's how:
    • With the dock set to auto-hide on the left, move the mouse to the very left edge of the screen. Right-click on the dock. This should bring up a menu, but instead causes GLX-Dock to hide.
    • Move the mouse to the edge to show the dock again, but this time, move the cursor one pixel from the left and right-click... the menu appears!

Hello and thank you for this bug report!

This is strange. But I think it's maybe better to continue this discussion on Launchpad
