@SGaist That seems to be the solution, haha! Thanks.

@JonB
Thanks.. found out, that i needed to create a new Pointer in the Declaration of the .h File..

Means..

TGS_Widget_AssetList * _assetList;

Wasn´t enough...
I needed to do:

TGS_Widget_AssetList *_assetList = new TGS_Widget_AssetList(this); or auto *_assetList = new TGS_Widget_AssetList(this);

Now it works.. i will update my initial post here

I am wondering whether there's some bad interaction between the 2017 build of Qt and your 2019 build of OpenCV. There should not as VS 2019 is backward compatible with 2017.

Latest version of the driver ?
Did you test using the nouveau driver ?

Hi
As far as i understand from google its a
LLVM bug but should be fixed a long time ago.

Would it be possible to update to a newer version?

Also, between it worked. and then stopped. can it be that you reboot the WM ?
(versus pausing it)

@VRonin I know about the methods that begin with __, I already changed

@Flavio-Mesquita Then please mark this thread as solved.
