I may have located the problem in xmesa2.c:
if (xmesa->xm_buffer->buffer != XIMAGE) {
/* back buffer is a pixmap */
xmesa->xm_buffer->back_clear_func = clear_back_pixmap;
}
If I leave this part out it works fine. Probaly the condition
xmesa->xm_buffer->buffer != XIMAGE
is fullfilled while it should not use the clear_back_pixmap function!!!
