Hi,
The attached file defines two application frames which differ essentially only in their use of with-first-quadrant-coordinates. In the one (BAR) without with-first-quadrant-coordinates, incremental redisplay behaves as I expect; in the other (FOO) with, strange things happen. I believe this is connected with output record moving; if I change state-matches-stream-p in incremental-redisplay to query both X and Y coordinates of the stream cursor, the display of both applications is as I expect.
Cheers,
Christophe
