Details

The window is transparent during playback and partially transparent (on both sides) when paused.

This is visible on the video: http://youtu.be/PKDyhZwRMxg

Changing playback drivers in Settings has no effect. Switching off compositing doesn't help - the
playback area is just gray instead of transparent. Changing "monitor background color" doesn't help.

The workaround I found on Ubuntu forum "XLIB_SKIP_ARGB_VISUALS=1 kdenlive" makes kdenlive crash.

My card from lspci:
00:02.0 VGA compatible controller: Intel Corporation Broadwell-U Integrated Graphics (rev 09)

Package version:
kdenlive-15.04.1-1
This task depends upon

Also reproduces on another machine with NVidia's card with the same kdenlive version:

01:00.0 VGA compatible controller: NVIDIA Corporation GF119M [Quadro NVS 4200M] (rev a1)

Let me check if my Qt style (QtCurve) has something to do with it…

It works when I don't use QtCurve's "opacity" setting.

Does it work with other qt5 themes?

I checked that it only has trouble with QtCurve and only if I change the transparency levels.
There's an information that the transparency can be source of problems, so it seems that it's QtCurve's problem.
I think this bug can be closed, then.
