Some Page Loads Slowly

[mattermon]

Configuration

Wolvic version: 1.4.1 Wolvic build ID: Hardware:

Steps to Reproduce

1. visit https://www.mzgf.com/world
2. open webvr content, such as https://vr.mzgf.com/?projectCode=00g1301M&projectType=ALL

Current Behavior

Page loads slowly, even up to minutes, as mentioned https://github.com/Igalia/wolvic/issues/548

Possible Solution

I have tried some methods

1. On gecko-dev project, revert some commits , means that use Mozilla offical release on branch FIREFOX_103_0_2_RELEASE Webvr content still loading slowly
2. On Wolvic project, remove dependencySubstitutions options in local.properties Webvr content loading normally, ignore webvr content abnormal

I doubt is there some build dependencies or the version difference of GeckoView after add dependencySubstitutions options?

When dependency susbtitutions are not used then this mean that you get the geckoview version from maven. Currently it's setup to use 105.0.20220822095220, is that what you're using?

BTW, it is not possible that you could load webxr content without the dependency substitutions, Wolvic will work in 2D browsing mode but won't allow you to load WebXR content.

1. Yes, when substitutions options not used, GeckoView version is 105.0.20220822095220.
2. When loading a WebXR/WebVR content, after page loaded, there will be a button such as "Enter VR" etc. Until the button clicked, will enter vr mode(Immersive Mode).

As far as I've seen that page is still using WebVR.

or maybe we need an UA override to get the proper WebXR version, I'll check that.

Hi svillar,

You are right，https://vr.mzgf.com/?projectCode=00g1301M&projectType=ALL is using WebVR. While as you have met in https://github.com/Igalia/wolvic/issues/548，the page loading very slow（before entering vrmode）. I wondered if this has relationship with WebVR or WebXR.

BR.

I tried to cherry picked #894. After modify UA for mzfg, it worked for entering immersive mdoe, it's great!

But, sorry for my poor English. Maybe I did not describe very clearly. What i meat is that, after click any page like https://vr.mzgf.com/?projectCode=00fli01M&projectType=ALL from https://www.mzgf.com/mj/world, it casts a long time before show anything(the whole page is white).
