This is a list of effects not working (tested in 23.08 beta appimage on a
Pop!_OS 22.04 system) in no particular order:

1) Video Waveform Monitor
   - Missing UI for tint0, tint1, fitmode, input (see effect description from
https://ffmpeg.org/ffmpeg-filters.html#waveform)
   - Parameters w/o visible effect: graticule, background opacity

2) Vectorscope (advanced)
   - Parameters w/o visible effect:  background opacity

3) Histogram
   - Missing UI for colors_mode (see effect description at
https://ffmpeg.org/ffmpeg-filters.html#histogram)
   - Parameters w/o visible effect: background opacity, foreground opacity

4) Datascope
   - Missing UI for components (see effect description at
https://ffmpeg.org/ffmpeg-filters.html#datascope) 
   - Parameters w/o visible effect: mode, format, opacity

5) CIE Scope
   - Missing UI for system, cie, gamuts, showwhite, corrgamma, fill (see effect
description at https://ffmpeg.org/ffmpeg-filters.html#ciescope)

6) Zoom Pan
   - Effect does not do anything (except zoom which oddly enough is based at
the top left corner) w/o the (missing) duration parameter (see effect
description at https://www.mltframework.org/plugins/FilterAvfilter-zoompan/

7) NDVI
   - Missing UI for parameter color map (0), visible channel (6), NIR channel
(7), index calculation (8), legend (9) (see effect description at
https://mltframework.github.io/mlt_web/plugins/FilterFrei0r-ndvi/)

8) Some values need to be entered twice to be properly displayed even though
the value was accepted and acted upon (tried it with X and Y fields in Crop by
Padding effect)

9) Edge Crop
   - Values entered in Top or Bottom are applied top AND bottom equally. The
last value entered in Top or Bottom is used.
   - Values entered in Left or Right are applied left AND right equally. The
last value entered in Left or Right is used.
   - As soon as a value is entered either in Top or Bottom, values in Left or
Right are ignored
   - Settings for Automatic center-crop and Use project resolution seem to be
ignored completely
   - Entering of values in Left most of the time requires two attempts
   - Using the sliders creates havoc with the cropping

10) Fill Borders
   - Missing fill options for reflect, wrap, fade, margins (see ffmpeg filter
description at https://ffmpeg.org/ffmpeg-filters.html#fillborders)

11) Shear
   - Parameters are of type integer when they should be of type float

12) Scroll
   - Mouse wheel in the value field does not change the value but the effect
shows a change in the Project Monitor
   - Sliders behave strangely (no change in the slider position or value but
Project Monitor shows effect is changing) when using the mouse wheel
