FWIW, I'm using the following config for it (in case it's related to the scaler settings or something...):

In 83b6f8e9:

SCUMM: Fix bad height for Indy 3 text box (bug #15484)

This was a recent regression. The last parameter to copyRectToScreen()
is the height, not the position, so it should not be adjusted by
_macScreenDrawOffset.

Thanks! This appears to be a recent regression, and it didn't crash on my computer so I never noticed. I think it should be fixed now. Please let me know if it's not.

Status: pendingclosed

Thanks for such a quick fix!

Yeah it looks like the OSX PPC port is sometimes "lucky" in the way it can catch some corruption issues.

I haven’t been able to trigger any new crash after this change, so far.

I think the issue can be closed. I’ll reopen it if necessary.
