Grid phenomenon is more serious with webgl

[jaccen]

When opening the browser and loading a glTF model for the first time, there might be a grid flickering phenomenon as shown in the figure. Sometimes, refreshing the page multiple times can make it disappear, but the specific reason is unknown. like the pic: web: chrome browser platform: windows or MacOS
