I solved some of the issues. The second grid is still not correctly scaling. Strictly speaking it scales fine but the scrollbar sends an extra WM_SIZE message that resizes the grid back :/

OK, I fixed the scrollbar problem just by disabling the message.

I hope I didn't break a lot of things.

No please close it. If a regression or another problem appears in the future, you can reopen the issue or post a new issue report.
