We're getting this too. PIXI 8.1.1 Device is Alcatel 1B (2020) Android 10

Searching online, it seems like this error can often accompany a context loss in WebGL. This can happen for a number of reasons, but perhaps out-of-memory? Does anyone have this device mentioned above that could confirm?

[erikdubbelboer]

It's indeed caused by a context loss. I can trigger it one in a while on https://dubbelboer.com/sillysky/ by running this line in the console:

document.getElementsByTagName('canvas')[0].getContext('webgl2').getExtension('WEBGL_lose_context').loseContext();

Hello

i have the same probleme here i try to use pixi js, video render cause problem this demo work fine on pixijs.com : https://pixijs.com/8.x/examples/sprite/video but locally with nextjs i have issue :

[aidevelopercode]

Hello devs, i fixed the pobleme by reset chrom flags, go to chrome://flags/ and reset to defaut params.

i think it's a problem with an experimental chome parameters

Also facing this problem, the website on iOS keeps reloading and leads to "A problem repeatedly occurred". Is there any proper way to handle context lost using pixi@v8?
