Is there anything I can do for this moire effect

On the left side of the video there is a keyboard that has some ventilation grills on the back of it. The grills in the image are very small so I believe QTGMC is deinterlacing the grill. I've included two videos, interlaced and deinterlaced, so it makes sense. It's causing some diagonal lines that are buzzing. Is there anything I can do, filter wise, to avoid this?

Try

ffms2("interlaced clip.mkv")  #or your source filter
AssumeBFF()
BWDIF(field=2,thr=0.8) #adjust the thr
QTGMC(InputType=2)  #for cleaning up
