CEF Forum

Hello,

In our team we use jcef for our javafx app to show some 3D plots that need webgl. The jcef works fine by most of us. But one of our colleages has no luck. The same project with same code has only black screen after the plots are generated.

Does anyone know the possible reason for that? Hardware or software problem?

We're using win7 64 Laptops and Jcef:
JCEF Version = 84.3.8.266
CEF Version = 84.3.8
Chromium Version = 84.0.4147.105

The problematic laptop's config and two cases screeshots are attached.

Does anyone know the possible reason for that? Hardware or software problem?

Likely a problem with their video card capabilities or drivers. Are they using the most current drivers available? You can also switch to software rendering by passing --disable-gpu in the command-line.

Thanks for reply. Yes, we updated the all drivers using intel driver assistant.
I've tried "--disable-gpu" but the webgl is completely not supported by the browser after that.


So, I think maybe the laptop is too old or any other suggestions?

Thank you very much.
