St-exp compiled from source 6th March.
When a graph label is long enough to overlap the border of the window the graph is in, the numbers are cut off at the edge of the window, although the box they should be displayed in isn't.
I have seen this behaviour in various places such as the finance window and the windows that can be opened by clicking on town halls or factories.
See this image
for a demonstration of the bug.
This was produced in a new game by clicking on a town hall and bringing up the population graph.
If a savegame is helpful, I have this behaviour in the games I have uploaded in my other bug reports, in the line management window for example.
