Question WebGL build randomly missing partial texts

Hi, I'm using Unity 2019.4.18f1 to develop for WebGL. In my project, I have to read multiple different texts from database and display them during runtime. And I also need to include both Chinese and English characters. However, sometimes in the build (browser is Chrome), there's randomly missing partial texts (like below), but sometimes everything's alright and nothing went missing. (In the editor, it never went wrong.)


(Both languages have missing texts.)

I noticed that when there're texts missing, the web console will print multiple warning "[.WebGL-000001E7A6E5EF40] GL_INVALID_VALUE: Offset overflows texture dimensions." at the same time. But I can't figure out what this message means.

If anyone has any idea about this, I'd really appreciate any hint or possible direction to solve this......my initial guess is this may be related to runtime memory restriction by WebGL or browser but still have no idea on how to solve this. Thanks in advance!

Edit: On Firefox, I get this warning "WebGL warning: texSubImage: Offset+size must be <= the size of the existing specified image.". I've tried to remove the msjh font asset and only use the default Arial font asset, and only use English characters, but I still run into this issue.

 

I've managed to make the warnings go away by setting the RectTransform of my Vertical Scroll View from -200 to 0, and most of the random text missing issue go away. Some still exist and I suspect that to be related to another web console warning "WebGL: INVALID_VALUE: tex(Sub)Image2D: video visible size is empty". After I disable my VideoPlayer in the scene, the texts don't go missing anymore.

 

I'm working with Unity2023.2 and still have this problem on WebGL. Do we have a solution for this yet?

 

I also missed some text (all text on different text components). Only in WebGL builds.
I solved it by deleting the "library" folder and the existing build. Then do a "clean build".

 

This is happening to me too, ever since adding VideoPlayer, some texts are not showing some characters

 

Tried this and didn't solve it for me
