Created attachment 145442 [details] Demonstration of strange placement of gaps. After some editing / adding of components to the panel, gaps appear to start leading their own life, and components seem to be placed at random. (free layout)
A restart of the IDE seems to fix the behaviour.
Can you get it to such state repeatedly? I.e. are there reliable steps this can be reproduce (from some initial state - form you could attach here)? Thanks.
We would at least need the sample GUI form that shows the strange gaps, not just screenshot. Otherwise I'm afraid we can't do much with this issue.
