Me, maru and yosh did some tests and here are the results:
non-ssh, sweden -> usa (yosh)- works
non-ssh, sweden -> .at (maru)- works
ssh, sweden -> usa (yosh)    - not work
ssh, sweden -> .at (maru)    - not work
ssh, sweden inside lan       - not work
non-ssh, inside lan          - works most of the times.. but not always
                               most often fails when displays are slow
local (DISPLAY=:0.0)         - works

I've tried the following locally:
Linux/x86 - 8, 16, 24bpp
Sun/sparc - 8, 24bpp
Irix/R4k  - 8, 24bpp (the 24bpp thing has like 1,2,4,8,12,24 but chose 24)

yosh and maru uses linux/x86 and 16bpp+ (iirc)

I don't think it's the latency alone, since non-ssh over the atlantic must
give more latency than with ssh but inside the lan...

My guess would be some timing-problem like the color-selector had before...

Source (to non-linux X) could pretty sure be dug out on demand..

Any clues? (and why does it _only_ affect pixmap-based themes?)
