On X11 for the color RTs in the video cluster, I noticed problems with
a) weird spacing of text
b) excessive redraw of windows.
I noticed this mainly when I was dealing with overlapping xterms and
zephyr notices. I am using "6x10" for xterms and "8x13" for zephyr.
In particular, occasionally the zephyr window will draw a line or partial
line of text in the 8x13 font but spaced horizontally on 6 pixel boundaries
(effectively squeezing together the text), and occasionally the xterm
window will draw a line or partial line in the 6x10 font but spaced horizontally
on 8 pixel boundaries (effectively expanding the text). Is it possible
that the X server gets confused when drawing these two size fonts in different
windows at the same time? I notice this most often when I move the zephyr
windows or xterm windows around using the window manager's function
"moveopaque" which constantly redraws the window being moved, and those
windows around it.
My line in my .uwmrc:
# FUNCTION KEYS CONTEXT MOUSE BUTTON ACTIONS
f.moveopaque= meta :window|icon: delta right
I know absolutely nothing about X, but one guess is that some code that
draws text uses globals incorrectly and should be made re-entrant (this may
be a stupid idea depending on the architecture of the X server).
Please mail me questions if you have trouble reproducing this bug. If worse
comes to worse, attach my home directory and source my .login and my
.cshrc, etc. and try moving windows as I described above.
These bugs do not affect the usability of the system at all for me; I am
simply reporting them for your information.
