Wobbly windows bounce continuously when snapped to panel

I've replicated this bug on an NVidia 8600GS Mobile with Visual Effects set to "Extra" which suggests this is compiz related. Changed the package to 'compiz' to reflect this.

I've replicated this bug on my wifes computer as well.

I have this bug too. I have an ATI 1600 Pro graphics card and I'm using the default free drivers.

By the way, it only bounces if one of the top corners is attached to the top and the other top corner is outside the screen! Same thing for bottom attachment.

This bug was nominated for Gutsy but does currently not qualify for a 7.10 stable release update (SRU) and the nomination is therefore declined.
According the the SRU policy, the fix should already be deployed and tested in the current development version before an update to the stable releases will be considered. With 7.10 now released, that policy applies to this bug. See: https://wiki.ubuntu.com/StableReleaseUpdates .
The bug is not being closed as work will continue on fixing it for the next release, Hardy Heron (8.04). If the state of this bug should change such that it qualifies for the SRU process, please contact the person who originally declined it and ask them to re-evaluate it. To help improve the state of this bug see: https://wiki.ubuntu.com/Bugs/HowToTriage .

Still a issue in intrepid. AFAIK, this bug can only be reproduced with "wobbly window" plugin enabled.

I reported the bug upstream, so compiz developers can see the issue and have the possibility to work on it.

There's a whole family of bugs of this kind with wobbly windows. One way of thinking about this is that the amount of wobbly-ness should be related to the amount of energy put into mouse movement - when the mouse stops moving for a while, the wobbly effects need to be damped out. There are numerous positions where a window can be slowly moved near other objects and a large amount of wobbling can persist indefinitely. One example is where a tall window is slowly moved so that the long edge is near a smaller window (about 1/3 the height of the tall window) - it appears that the two corners of the small window attract the tall window edge in such a way that the tall window's edge vibrates wildly.

In a similar way, the attraction to other windows should diminish with time, so that a small adjustment of a window is possible.

Still reproducible under jaunty, but "sticking to panel" is disabled by default, even with extra effects. It can only be enabled with tools such as ccsm.

I made a video of this and other issues to do with compiz on extra.

1: When a windows is near the top or bottom menus, and has one side out side the screen, it's corners will start to wobble.
2: Tall windows will some times start to jump from the top menu to the bottom menu repetidly.
3: When a window is animating it's visual and clickable area are ofthen not in the same location.
4: Tall windows are hard to move from the bottom to the top or vis versa, as they stick to the othere end.
5: Sometimes windows will jump behind the top menu, leaving the user unable to use the functions found in the title bar of the program (minimise, close, maximize and move), not all users knows that this can also be done from the content menu for the program in the bottom menu.
All theas bugs are confirmed (by me) on 7.10, 8.04.1 and 8.10, on two different systems.
The solution to the most critical of thease issues is to only tell compiz about the desktop (screen - menus) space and not the screen space, this would avoice that the program jumps behind the menu, wobels and reduce the jumping and flickering of the windows in general.

I will just confirm #5, it wobbles up under the top list, still in 9.04.

Great work!

Nice job!

Not sure if this should be reported as a separate bug but it is certainly *very* similar:
on maverick (beta), with dual monitor setup where monitors have slightly different sizes, when a window is placed near the edge of a "bigger" (pixel-wise) screen, it starts to wobble alternately snapping to the real edge of the screen and to an invisible line a centimeter or so away from the edge.

This started after a recent update when support for screens with different resolutions was re-enabled.
