Nervous (constantly shaking) windows

[tendays]

Hello, I am new around here so, apologises if I break forum rules or something. Is this the right place to post bugs?

When I do the following:
1. Maximise a window vertically,
2. Move it horizontally to almost (but not quite) touch a screen border, the left or the right one,

it starts repeatedly snapping and unsnapping to the border. If I restore (unmaximise) it, it keeps doing it.
Whether I restore it or not, it stops shaking only after I move it.

This only happens when "wobbly windows" option is active. Similar if I maximise it horizontally and go to the top or bottom screen edge.

I left the friction and spring constant options to the default. I'm using Compiz 0.5.3 on Kubuntu 7.04 Feisty.

depends on your issue....

if it's an installation issue, then such that problem is posted in the installation section
if it's a problem associated with general usage, it goes in this section
if you saw some setting you can't reproduce, then it goes in configuration section
:D

(you have it right this time :))

hmmm.....

Is it a wobbly kind of shake ??

or just the window just snapping back and forth between the borders?

try disabling the "snapping windows" plugin

try disabling the "snapping windows" pluginWhen using Wobbly Windows, you cannot possibly be using Snapping Windows, since only one of the two can be enabled at once. Wobbly has its own snapping function; Snapping Windows exists specifically for users who have disabled Wobbly and still want snapping functionality.

Instead, please check your settings for the Wobbly Windows plugin, specifically making sure that the Snap Inverted option is disabled. This option, when enabled, causes windows to snap to edges (of the screen and of windows) by default. When disabled, they will only do this when the Snap windows key (also set in Wobbly) is held down.

oops, my bad

The problem only occurs with "wobbly windows". As Fyda mentioned I can't simultaneously have the "snapping windows".

If instead I have the "snapping windows" plug-in but not wobbly windows, the problem does not occur.

If I activate the "snap inverted" option, the problem is only triggerred if I press the shift key (i.e. when I cause a snapping to occur).

My interpretation of what happens is the following:

1. A partially (i.e. horizontally or vertically but not both) maximised window is moved next in a position where snapping should occur (if "snap inverted" is active then I need to have "shift" pressed)
2. Because the window is in the process of being moved and is close to a border, the "snap" feature of the "wobbly windows" plug-in is triggered
3. A snapping animation occurs (the window gradually stretches to touch the border)
4. Compiz somehow forgets to actually move the window. As a consequence (because the window stays in a position where it should be snapped) we're back to step 2.

When I increase the friction constant to the maximal value (10 instead of 4) I can see that step 3 takes a longer time, and, at step 4, the window seems to be displayed at the actual position again, before (when we're back to step 3) starting to stretch again.

Note that it happens both on screen border or when touching another window.

I should also mention that, when it is caught into that loop, un-maximising it doesn't help - it only stops shaking once I've alt-button1-moved it away from that border.

(Can you reproduce this or is it only happening to me?)

Thanks!

I've had this bug happening for as long as I can remember.
