MobaXterm does not display the whole image received from WSL

Question

I am using WSL1 in Windows 10 with Ubuntu 18.04 LTS.
Configured everything fine to use OpenCV with C++, but when I wanted to display an image, I always received the below error.

terminate called after throwing an instance of 'cv::Exception'
  what():  OpenCV(4.5.5-dev) /opt/opencv/modules/highgui/src/window_gtk.cpp:635: error: (-2:Unspecified error) Can't initialize GTK backend in function 'cvInitSystem'

After searching on the internet, I've found that I should use some kind of X Server to display the images, so I've installed MobaXterm to try it out. I have also added the export DISPLAY=:0.0 to the ~/.bashrc file.

Now, when I try to display my image, a window pops up, but only a part of the image is displayed.

Does anyone have any idea what should be the problem, why is only a part displayed of the image?
Thank's for everything in advance!

Are you using WSL1 or WSL2? In the question you highlighted that you use WSL1 but in the tag list you mentioned WSL2. — Jakob Stark, Feb 19 '22 at 11:21
I am using WSL1, I have tagged WSL2 because there was no WSL1 tag. — Geri Papp, Feb 19 '22 at 12:18

Maybe you can try with another option such as gWSL or XShell? If these are working, then it would be probably an issue related with MobaXterm and you can contact with the developer of this application. If the problem continues, then it should be further investigated.

So, I did not find out the solution for the problem, but I have installed VcXsrv, and everything is working fine, there is no display problem with it. Thank's for the hint. – Geri Papp Feb 23 '22 at 09:03
