Post subject:  Strange glitches (UA6540+UA6541)

Has anyone ever seen something like this on official consoles or any clones?

It's the very first nes PPU clone made by UMC in 1988. It is interesting to understand: this is the feature of this sample or such glitches - the reason for which UMC released fixed UA6538 in '89. What does it look like to you?
