I added a Slideshow clip to project. Turned on "dissolve" transition. The parameter's value was default (1s). I started preview. There were transition between slides. Then I changed that parameter to 2s. Started preview again. And then there were no transitions between slides at all. Changing it back to 1s didn't help.

I've started a thread about it there: https://forum.kde.org/viewtopic.php?f=270&t=136486

one problem with the slideshow transition duration might be, that when the slideshow is created the property "luma_duration" is set to a value in the timecode but when the producerqueue sets the "duration" property for the luma filter it just grabs that timecode as a string and then calls .toInt() which seems to result in the duration being "0".

[from src/mltcontroller/producerqueue.cpp, lines 531 and 533]
QString luma_duration = EffectsList::property(info.xml,QStringLiteral("luma_duration"));
if (!luma_duration.isEmpty()) filter->set("duration", luma_duration.toInt());
