Description Timm 2021-10-14 06:59:23 UTC
SUMMARY
Using the transition effects Wipe and Dissolve on a title clip with one having typwriter (through I tried without as well) created the Error Message "Redering crashed"

STEPS TO REPRODUCE
1. Create Title Clip (eventually with typewriter anymation)
2. Add transition (Wipe and/or Dissolve) to V1 incl. Audio
3. try to export MP4 e.g. Video

OBSERVED RESULT

```
Rendering of <file>.mp4 crashed

mlt_repository_init: failed to dlopen /usr/lib/mlt-7/libmltsdl.so (/usr/lib/mlt-7/libmltsdl.so: undefined symbol: XGetWindowAttributes)
[mp3 @ 0x55641649dd00] Estimating duration from bitrate, this may be inaccurate
[mp3 @ 0x5564164a5280] Estimating duration from bitrate, this may be inaccurate
(process:69548): Gtk-WARNING **: 08:09:15.821: Locale not supported by C library. Using the fallback 'C' locale.
[consumer avformat] Could not open '<file>.mp4'
```


EXPECTED RESULT
Clean video rendering should start and finish

SOFTWARE/OS VERSIONS

running Linux Manjaro Arch, tried with 21.08.1, 21.08.2 and unstable 21.11 AppImage
MLT 7 → I had MLT6 installed for other software but even removed this, checked also the settings of Environment etc. → nothing helped until I nailed it down to the title clips. Even tried different Export formats and compiled from Git Repository myself etc.

Using:
MLT version 7.0.0
FFmpeg libraries

KDE Frameworks 5.86.0
Qt 5.15.2 (kompiliert gegen 5.15.2)
Das xcb Fenstersystem

ADDITIONAL INFORMATION

It almost killed my project so I had very little time to reproduce, but I hope this already helps tracking the bug down. (sorry for this short issue report, in a rush, could not find a similar other bug report)
