Hi all,
For those who are testing the native windows XDRIVER, there are some strange
behaviors which still need to be fixed. Some suggestions if you run into
trouble:
d.zoom seems to act strangely and zooms in too far sometimes (I think we
need to correct Pixmap to screen conversion, I just haven't had a chance to
look): To fix improper zooms, either use g.region or fix with an X Window
version. You can also usually zoom out several times to fix it. For now
don't zoom in to too a small region.
Sometimes the screen doesn't refresh when expected. Resizing the screen
'usually' refreshes the screen, but for me only stretching horizontally, not
vertically. So to do a redraw grab the side of the window and resize it a
bit. (I have partial fix for this, but will need to do more testing and fix
the other RESIZE/REPAINT events before submitting)
There are other strange behaviors, but right now I don't have my linux
version to compare to so I'm not sure what is the correct behavior. Please
report problems as you find them to this list.
Be sure that you are using the latest version, since there were some fatal
errors from the original version.
