Sorry, the behaviour I reported is caused by something else. I copied the cell code that produced different plots at every evaluation into a new notebook and got consistent results every time. Even copying and pasting into a new cell got rid of the random behaviour of the axes. Very weird. I take it back then and stop blaming the plot command for this. The issue about disappearing axes ticks that you commented on below would be great to fix, though. It may be easier than solving ticket #5448, so I hope someone will do it. Thanks again for helping me track down the issue.
