Hello Hainzgrimmer,

I am going to go through each issue individually. But overall I was unable to reproduce most of the issues you have described on our end. I have some general questions for you, as well as some specific to each issue which I will address separately.

  1. I tested these issues using the 4.16.1 binary build of our engine (From our Epic Games Launcher) and tested the HTML via Firefox 64 bit (53.0). Did these HTML 5 issues occur for you in other versions of the engine or Firefox?
  2. Do you have any screenshots of the distortions you are experiencing?
  3. Could you provide your DxDiag?

Issue 0: Initial bullet list

Following the repro steps, you provided in this initial steps did not reproduce your issue on our end. On my end, there were no visible distortions. I have specific questions for these steps.

  1. How long after making the project fullscreen did you close it?

Issue 1: Untick the enable FOV scaling in Project Settings

I was uanble to reproduce the issue with the steps for this issue.

  1. Were there any other settings changed other than FOV scaling for testing this issue?

Issue 2: Using the Epic Zen Demo code

Copying the code from the Demo into the project I created did not cause any distortions.

  1. Did you change any values in the code that was copied over?

Issue 3: Change the value of canvaswindowusehighDPI

Following the steps provided did not reproduce the issue on our end.

  1. Where specifically did you change the value in the code that caused the issue?

Issue 4: Change value of canvasWindowScaleMode

I was able to see some distortion when the value was set to 1 (Screen became squished) but using a value of 2 did not cause any distortion.

  1. When the value is set to 2 on your end, what is the distortion you are seeing?

Thanks!
