Public bug reported:
If you draw a stippled object on a TclTk canvas with negative
coordinates, and scroll to display it, the appearance of the stipple is
not that of the specified bitmap but looks like uninitialized data. See
attached code and screenshot. The actual pattern is different each time.
The same code on the same machine will produce the correct display if
the window is on a different Xorg server.
Code:
#!/usr/bin/wish
pack [canvas .c -scrollregion {-1000 -1000 0 0} -bg beige]
.c create rect -900 -900 -600 -700 -fill blue -stipple gray25
.c xview moveto 0.05
