Window size jumps unpredictably when using the resize handle

[Carlos C.]

Binary package hint: compiz

See the attached screen-shots, each showing a state right after pressing the mouse button on the bottom right corner of the window decoration, where the pointer changes to a 90 degrees angle + arrow (on the screen-shots it just shows the normal pointer). If I then move the mouse while holding the button down, it changes the size of the 'mask', relatively to the pointer, that is, the lower right edge of the mask always stays right/below of the pointer.

This does not happen always, but quite often. I couldn't yet figure out how to reliably reproduce this.

It seems that is related to the extra grab handles at the windows' lower right corner, as I can only make it happen when scaling windows at these handles.

Notice that when you click on these handles somewhere INSIDE the window and release the mouse button again, without having moved the mouse, the window will be resized by a few pixels anyway in most of the cases. So perhaps the size jumping up as extremely as in the screen-shots, is just an extreme case of this wrong behavior.
