The screen flickers in tile view. At this time, the screen status is marked as inactive.
I set preferH264: true, disableH264: false in config.js.

Is there any way?

Do you host the jitsi server yourself? Are you using a TURN server?
Does the flickering occur everytime another user joins?

Yes. Use jitsi-meet-docker self-hosting.
Do not use the TURN server.
If there are 3-4 or more participants, an inactive black screen occurs randomly.

For the test, I opened 5 Chrome browsers on my computer and proceeded to view tile view.

So you test from the same computer and at some point you start getting some thumbs black?
I would say that is normal, all participants are sending from the same PC and they affect each others bandwidth …

Why is this normal?

Bandwidth seems to be sufficient.

And the same thing is happening on the current jitsi meet site.

Evidently bandwidth is not sufficient if you’re experiencing the same thing on meet.jit.si. You’ve presented this same issue in like 5 different posts and the response has been the same. If you still doubt it, have other people join you from different networks and see if you report the same issue.

Did you found a solution for this problem?
