TAdvStringGrid: Repaint and CellAlignment issues

Some days ago I updated the VCL Component pack on my computer an realized some really strange behavior of the TAdvStringGrid. Some Cells which where always LeftAlign are now centered ... and on some Computer it looks like Windows got some trouble in painting cells ... it's always different. The repainting Issue happend as far as i can see on XP Systems, while the alignment issue is every where ...

I haven't changed the code an ti worked for years now ... :-) ... any idea how to fix this?

Thank you!

It is unclear what is causing this.
Can you please provide some more details? Do you use grid.Alignments[] ?  the event OnGetAlignment ? Is AutoNumAlign = true ?  Steps to reproduce this starting from a default grid?
