Hello everyone.
This is my first time posting here and I'm doing it after googling for several days trying to see if there is any kind of solution.
I'm running Kdenlive 19.12.3 in a Windows x64 laptop with the following characteristics:
Intel Core i7 4712MQ
16GB RAM
Intel HD 4600 / Nvidia GeForce 820M
Everything seems to work well until I try to display any of these tools: Histogram, Vectorscope, RVA. When I activate them, via View->Histogram. The embedded window that appears is completely black and when playing the clip in the Project Monitor, the clip appears zoomed (maybe 1:1?). If I deactivate these tools, everything goes back to run well.
Is it a bug? Am I missing something in the use of these tools?

Thanks.

edited the post.. i have already opened the issue.. ( just to speed up the fix )

[EDIT] making some tests... seems that is related to the Directx backend... using OPENGL the views are correctly "populated"
