Bugs: windows & the display setting

Turning redraw off by calling

set_window(["display", False])

can be a very slow command especially if running remote. It may be faster to start with the window display off, or if grouping commands in atomic units, use undo buffers.

This is most noticeable on axes tick labels, but can also be seen with other text.

Workaround:

Try changing the window display to True before calling print_window; e.g.

set_window(['display', True])

However, to increase speed the contents of the chips window are not refreshed. So while nothing is drawn to the window, if the window is obscured by another window, the obscured pixels are lost and will not be refreshed if the obscured part is made visible again. That part of the chips window will be black.

Calling undo after deleting a window which had its redraw parameter set to False will re-create the window but display all its contents on screen.
