If datagrid is partially off of screen, vertical scrolling generates text overlapping, so the content of cells is unreadable.
The same problem is also with horizontal scrolling.
Note: vertical problem is show when the window is bottom side off-screen, horizontal one when is left/right side off

How to repeat:
Execute a query with enough rows to activate vertical scrolling, then drag down the windows partially off of the screen.
Now scroll down the grid (mouse scroller or arrow down).
I get text overlapping (Win7x64)

Please, check if the same problem happens when you start Workbench from the command line with -swrendering option.

No changes, still overlapping.

I can repeat this in Win7 inside vmware.

I'm afraid we cannot fix this. The problem is caused by the underlying .NET control we use (DataGridView), whose behavior we cannot change.
