Aterm resize very slow with option -sh (background image shading)

[Valéry Febvre]

Hi,

If I launch an aterm with option -sh (background image shading) and
then, try to resize it, the aterm's redraw is very slow and blinks.
Did somebody already note this problem?

aterm command example: aterm -tr -sh 70
I've this problem with ALL openbox alpha releases.

My environment:
xfree-4.3.0 with ATI rage pro mobility (problem exists with and without
2D/3D acceleration)
linux-2.4.21
Openbox 3 alpha X
