WebGL not working for Chrome

Unity Engine
1

I’ve been having an issue trying to get WebGL to work on my chrome browser. It stopped working a few weeks ago and I haven’t been able to figure out why.

I went and updated my graphics card to the latest drivers, (Nvidia Quadro NVS 450 on Windows 10 64 Bit) to version 342. I test out webglreport.com on Firefox and it shows it’s working, I try on Chrome it is not. I’ve gone to chrome://settings and enabled hardware acceleration when available, under chrome://flags the “Disable WebGL” option is no longer there, but I did enable override software rendering list. Under the gpu section it says WebGL: Hardware accelerated. So everything looks right, but it just wont work in chrome. Any tips?

This is what is under my chrome://gpu problem’s detected tab. Problems Detected Always call glUseProgram after a successful link to avoid a driver bug: 349137 Applied Workarounds: use_current_program_after_successful_link

Hello,

I also noticed this today. Somehow the version 54 of Chrome does not seem to be supporting WebGL in some machines in our office.

We’re still investigating this issue further, but I suspect some new GPU blacklisting for Chrome…

Even though this is not directly related to the Unity Engine. Could we get some support from Unity on why this is happening?

henriqueranj,

You are a savior my friend, downloading an older version of Chrome is a decent temporary fix, thank you.

Glad to know I helped you find the issue :slight_smile:

Also this has been discussed in another thread here: Last version Chrom 54 and webgl not supported message - Unity Engine - Unity Discussions
