Comment (by Elon Musk):
Adding 1 or 2 null filters at right spot fixes issue for me:
ffplay -f lavfi -i
"color=color=#000000:rate=25:size=400x400,format=yuv444p,setpts=N[b];color=color=#ffffff:rate=25:size=100x100,format=yuv444p,scale=width=iw+n:height=ih+n:eval=frame[w];color=color=#ff0000:rate=25,format=yuv444p[r];[r][w]scale2ref=eval=frame[r][w];[w]null[w];[r]null[r];[w][r]overlay=format=auto,setpts=N[w];[b][w]overlay=format=auto"
