Distorted avisynth preview

[Selur]

You are using the Avisynth FilterView not the normal Avisynth Preview.
-> Does the normal Avisynth Preview work?

Looking at the script used for the preview:

LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\LoadDll.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\DGDecode.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\TIVTC.dll")
LoadPlugin("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\unblock.dll")
LoadDLL("C:\PROGRA~1\Hybrid\32bit\AVISYN~1\libfftw3f-3.dll")
SetFilterMTMode("DEFAULT_MT_MODE", MT_MULTI_INSTANCE)
# loading source: H:\!_Video\Video_Mus\4 Non Blondes\1993 - What`s Up.vob
#  input color sampling YV12
#  input luminance scale tv
Source = MPEG2Source(d2v="E:\Temp\vob_e403183f84cb79aba8cda632a1294af7_6334.d2v",info=3)
# current resolution: 720x480
SourceFiltered = Source
# deinterlacing
Source = Source.TFM(mChroma=true)
Source = Source.TDecimate(cycleR=1,cycle=5)
SourceFiltered = SourceFiltered.TFM(mChroma=true)
SourceFiltered = SourceFiltered.TDecimate(cycleR=1,cycle=5)
# cropping to 690x464
SourceFiltered = SourceFiltered.Crop(14,8,-16,-8).PointResize(692,464) # point resize part is only used for preview; workaround for a bug in avsViewer
# current resolution: 692x464  (SourceFiltered)
Source = Source.Crop(14,8,-16,-8).PointResize(692,464) # point resize part is only used for preview; workaround for a bug in avsViewer
# current resolution: 692x464  (Source)
# filtering
# scaling
Source = Source.BicubicResize(720,546)
# current resolution: 720x546
# using lanczos resize instead of nnedi3 since width after cropping isn't mod4
SourceFiltered = SourceFiltered.LanczosResize(720,546)
# stacking horizontal for filter preview
SourceFiltered = SourceFiltered.ConvertToRGB32(matrix="Rec601")
Source = Source.ConvertToRGB32(matrix="Rec601")
StackHorizontal(Source, SourceFiltered)

No clue why this is happening.
-> would need a small sample of the source to reproduce.
