| don't all resize the window right away to enforce the new hints. |
| |
| Some of them resize only after: |
| - A user-initiated move or resize |
| - A code-initiated move or resize |
| - Hiding & showing window (Unmap & map) |
| |
| The following move & resize seems to help a lot of WMs that didn't |
| properly update after the hints were changed. We don't do a |
| hide/show, because there are supposedly subtle problems with doing so |
| and transitioning from windowed to fullscreen in Unity. |
