Re: MLA GFX: Double buffering does not always work
When double buffering is used, then the same updates must be applied to Both buffers:
When a display update is done in one buffer, and the display is changed to show this buffer,
then the buffer that is now inactive must also be updated.
Either by copying whole or part of the active buffer to inactive buffer,
or performing the same updates again on the now inactive buffer.
Even if double buffering shall give smoother display, it means more processing and more complicated code.
