I am new here so I hope this is the eight place for this post.

I just installed kdenlive to my Ubuntu 19.01. It is opening and opening vidoes but everything is white. The workspace, buttons, everything. I tried to go to theme the the color theme option is greyed out.

How do I change the theme so I am able to see all the buttons?

I used the ppa/ terminal way of installation. Not sure if this really matters.

what version of kdenlive are you using?

It says version 4:19.12.2-ubuntu19.10.1

This mean that themes folder can't be accessed by Kdenlive, do you have granted read/write permissions to the appimage?

can you try the 2019 version of Kdenlive? https://files.kde.org/kdenlive/release/ ... 4.appimage

Man.... I had this problem for a long time and finally found the solution. This should be in a wiki or something.
The problem is (well at least it was in my case) that you are missing the Breeze Icon theme. So just install Breeze and you are done

sudo apt-get update
sudo apt-get install breeze

Hope this helps.

EDIT:
To clarify if anyone from the Kdenlive team is reading this. I use Ubuntu 19.10 and I did not have this problem when I installed the version from the Ubuntu repository. However, after I added the Kdenlive ppa, I encountered this problem. I guess you need to make sure that Breeze gets installed with kdenlive too when installing from Kdenlive ppa.

on Linux there is not the "Force breeze icon them" flag?

BTW i hope that this topic can help someone in future
