Incorrect position on the screen in portrait mode

Thanks for this tool, I've been using it for a long time.

Recently I discovered in portrait mode it still thinks the resolution is 1920x1200, while in fact it's 1200x1920 🙂

This is only reproducible when you select an item while on the screen in landscape mode and launch xwinmosaic again on the screen in portrait mode (xwinmosaic will be seen as cut off from the right side of the screen). But if you do the latter once again, it will detect screen dimensions properly.

I recently switched from intel to modesetting driver, and can't reproduce this anymore.
