Hi Verge3D Team,
There is an issue with the antialiasing system. When a Verge3D scene is in an iFrame and the user presses the fullscreen button, the antialiasing does not always work as it should. Sometimes the antialiasing produces a very fuzzy result. I have attached a video of this issue.
I have been able to reproduce this issue on Chrome and in Firefox on Windows 10 with a discrete NVidia GPU and on Mac OS in Chrome running a discrete AMD GPU. Both systems are fully patched and running the latest drivers.
My test scene was made using Verge3D 3.1.1, but I believe that this issue goes way back.
The fullscreen antialias issue does not always occur. It seems to happen at random. On my systems, it seems to occur about 50% of the time. I have not discovered a pattern to reproduce the error reliably. You may need to enter and leave fullscreen mode a few times to provoke the error.
I have posted my test project to the Verge3D CDN. Here is a link to the parent page:
https://cdn.soft8soft.com/AROAJSY2GOEHMOFUVPIOE:2ae2540421/ext/verge3d_applications/full_screen_antialias_test/index.html
This project uses puzzles to disable the antialiasing when resizing the window. There is a timer that starts the antialiasing 1 second after user interaction stops.
Please let me know if you can reproduce this issue.
Thank you!
