English Amiga Board - View Single Post - Distorted sprites on OCS and invisible on ECS

I have a problem with sprites and tried some thousand different things without finding any clue to what's happening...

Now I'm aware of the OCS bug with sprites 6-7 and I'm staying away from them. But here the problem is with sprites 4-5 as they are vertically stretched. Now I could say I've invented some new real-time bitmap stretching technique but it wasn't my intention

So this is a test screen to show what's happening, numbers "12" are the same bitmap data and are sprites 00 and 04, why on earth #4 is double in height?

Then the "K" is sprite 01 and the red dot is sprite 03, all normal.

but there's even more, on ECS/AGA sprites 00 and 04 simply don't show at all...

Some help anyone, please?
