This only happens if CONFIG_WIN_DOUBLE_BUF=n. In that case we allocate the window bitmap with flag bmpf_direct_output.
The problem is that we allocate the window bitmap before we resize the window. We cannot map the window with the new size before it has been resized, so the operation fails.
We need to allocate the bitmap after the window has been resized. Not sure if it is worth handling each case (direct map or not) separately, or just always allocate the bitmap after the fact.
