hello please help me, i have a glitch on my P5 panel (32x64), 2 chain length. how to solve this glitch?
i use classic configuration on raspberry pi 3B for this case because my panel does not have pin E. Is there any hardware/code solution to eliminate this glitch effect? thanks and sorry for my poor English

Looks like a signal issue. Try gpio slowdown command line option. could be your cables are too long.

You can also use different ribbon cables, but ultimately there is a ribbon length issue. gpio slowdown will help, to a point.
Please re-open if appropriate, but otherwise not much more help we can give, it's really looking like a hardware issue.
