This is what it looks like using your method.
Same situation.
Mouse is missing and all solid tab gone.

Then you are doing something wrong. I literally did EXACTLY what I already told you to do and it works lol. I just formatted my pc to install Windows 10 Insider Preview build last night and for the 8th time, those steps have worked to get MQ6 in Jarvis. Maybe it's because I've started fresh every time? Make sure you delete your userdata folder before installing Helix 14.2. If you still can't get it to work, let me know. I'll make a video for you, but I am not doing anything other than what I have already posted.

Let me see the video?

It is working,as you can see on the image above,that the only issue that i am having.
The mouse movement and solid image underneath the letters.

Ok, I will make a video for you. It's working yes, but it should look EXACTLY like it does on Helix. Let me download a recording app and I'll get back to you later today. It probably won't be until late PM (In california here).
