How it looks in Wine

To reproduce:

1. Launch IDA, have it maximized
2. Open a file, so that IDA begins analysis
3. Unmaximize main window
4. See lack of scrollbars in the MDI, despite child windows being too large to
fit.
5. Compare the same with Windows and see that there it does have the
scrollbars.

The only thing I get in the console is this:
fixme:win:LockWindowUpdate (0x500c4), partial stub!
fixme:win:LockWindowUpdate ((nil)), partial stub!
fixme:win:LockWindowUpdate (0x500c4), partial stub!
fixme:win:LockWindowUpdate ((nil)), partial stub!
