Yes, I got the crash with the AppImage

My settings are the same as those indicated in the link you posted, but for the
melt executable. The link you posted indicates /usr/local/bin/melt-7, mine is
/usr/bin/melt (which is a symlink to /usr/bin/melt-7).
See attached screenshot in Comment 20.

Do you get this crash rendering with the AppImage? It looks like MLT is not on
the minimum version needed (version 7.0 or newer). 

If you rendered with the AppImage please check if the paths are set correct.
Goto settings -> configure Kdenlive -> environment. See the settings for the
AppImage here:

I tried with AppImage 21.12.3: it actually works correctly!!

Everything was perfect until I tried to render: unfortunately the rendering
process crashes with this error:
/usr/bin/melt: /tmp/.mount_kdenliDWCYjf/usr/lib/libmlt-7.so.7: version
`MLT_7.0.0' not found (required by /usr/bin/melt) /usr/bin/melt:
/tmp/.mount_kdenliDWCYjf/usr/lib/libmlt-7.so.7: version `MLT_0.8.8' not found
(required by /usr/bin/melt)

So, let alone the problem with the AppImage and the libmlt-7 library, what is
the problem with the native Kdenlive package in Opensuse Tumleweed?

Thank you emohr for your reply, but why should an earlier release solve my
problem?

I still have the bug in Kdenlive 22.04.0.
The bug is in the titler, and it happens with every font that has overlapping
segments, as Safa Alfulaij said in comment 8.
When editing text in the title clip everything seems smooth, but then the video
shows inverted color where the text segments overlap.

More investigation:
It's not a problem with Arabic or western, it's a problem with overlapping line
segments.
For example, applying the underline attribute to a pure English text inverses
the "filling" in the characters.
For Arabic, the letters aren't spaced (it's the usual and correct look), but
there are overlapping shapes (which is normal) whenever two letters are
"connected" together.
That's why the curve shape at one edge of the break appears, that's how the
letters are made and designed in fonts.

Check: http://i.imgur.com/5Zi45vb.png (Ligatures and kerning is working fine)
Arabic text in edit mode: http://i.imgur.com/4tnefCx.png (It's the same text
but doesn't have that empty areas)

Thank you sll for the information. This then would break also ligatures and
kerning in western languages too.

The titler needs to render the characters as a single QString, otherwise Qt
cannot apply its text shaping algorithms. Rendering characters individually
will break not only Arabic, but also many Brahmi scripts.

Tested Windows version:
The letter spacing should be increased, and that depends on the font it self.
But it doesn't solve the problem 100% complete.
The text while editing is correct and doesn't have breaks in it. It just have
breaks when it's painted to be used and not edited (clicking on the background
of the text clip dialog, for example)
Sample text: "تجربة لنص عربي"

Maybe this [1] is the related slot, but not sure what's the problem there.

Qusay, is character spacing set to 0 or another value? Can you work around the

Qusay, do you refer to Kdenlive's titler for creating title clips?
