Thanks!! Can this affect my browsing performance in pages using webGL 1.0.2?

I get the same behaviour in a Lanix alpha 950 device, please help! This don't occurs with chrome browser

Android Version: 8.0.0

Phone model and manufacturer: Samsung s7

Your version of Opera for Android: 49.2.2361 (beta and stable)

If the problem is with a page, a link to it: web.basemark.com/run/

If ad-blocker is enabled or not: both, enabled or disabled

If data savings is enabled or not: both, enabled or disabled

A description of the problem, including as much as information as possible:
When the browser runs the test for WebGL 1.0.2 in the page mentioned above, the notification: "web.basemark.com stops responding, Do you want to close the tab?" apears several times and the system become too slow
