Meta browser problem?

I am testing with Quest2.

Meta browser does not show the model.
However, it is capturing something with cursor.

FireFox browser shows the model.

The demo Tuscany was visible in both browsers.

Is it a configuration issue?

Sorry for my poor English.
Thank you.

I write because I was able to solve the problem.

Texture size and like.

The first pixel is, Over 8000x8000 .
When the pixel size was reduced, it was displayed in the meta-browser.

Pixel size is 7800x7800 .
Of course, the small ones were OK.
(However, 7900x7900 was dark.)

If it helps anyone.
