Hello Terry,
Back on Hal 4.5, I used to occasionally see a pattern like the one you describe. It would sometimes appear in the Haptek window when a Haptek People Putty character was chosen (when it happened, the character background would not display properly). I used to be able to make it go away by re-starting Hal as the only application running. However, I haven't seen anything like that phenomenon on Hal 5.
There is evidently something different about the interaction of your graphics card with the content of the Hal skins, as opposed to anything else displayed by your video card and monitor. (I am going on the premise that you never see these patterns at any other time, or on any other content besides the Hal skins.)
Other forum members: Do any of you use the same video card that Terry has listed above? Have any of you ever seen flashing multi-colored patterns on the Hal skins? Do any of you have a way to fix it, or a theory that could lead to fixing it?
Sincerely,
Don
