Is this a known bug?
I believe this bug is in the X server, but how do I prove it... 

I'm using a PutImage protocol request with format=bitmap aimed at a window
on the color screen (8 bit per pixel) of a Sun Sparcstation. (X11R3 (MIT);
SunOs 4.0.3)

Executing the request partly works: Bits are painted first, but then the
rightmost part (looks like left_pad pixels) of the image is restored again
to something which looks like the previous contents but blurred a little.  
It also looks a little funny that the window is painted in two steps.

I know I have not given a reasonable test case.  Excuse me, I'm not a C
programmer; my Cedar test case might not help you anyway.
