Video quality looks like discotheque


I have no idea where to ask this. But I am having issues with ZOOM sometimes.

It is not always, but during a meeting my ZOOM screen all of a sudden starts to look like a discotheque. The screen flashes, it makes me 'hang' and all kinds of colors are being shown.

Any idea what this could be?

Luckily it doesn't happen all the time and it doesn't affect the sound yet this is not how it is supposed to be.

Hope someone can help me out 🙂



maria, I am experiencing a similar issue and do not know if it is ZOOM , ATT, or Windows related.  I am running my PC on Windows 11.0, with 5G Broadband from ATT, and the latest upgrades I can find.  However, video lags and freezes, audio needs speech therapy, and the folks on ZOOM with me are trying to be polite but my system is disrupting the flow.   I requested a test thru the Zoom Connectivity Tool, only to receive a response that I should contact the community.    Have you any ideas?

I am far from good with computers so I hoped to get some answers here. But I am sorry to read you are having similar problems. Hope we get a solution here soon! 


I have exactly the same problem.

This is really a problem as I am teaching with zoom.

I have contacted the support and am waiting for an answer 

That must be really hard. It doesn't happen all the time but still.. I can imagine it disrupts.
Great you contacted support. I would be happy to know their answer.


That must truly be disruptive to your process.


Thank you! I saw that other people described the same problem here. Some of them tried to re-install zoom

This makes me laugh so much: psychedelic colors 😂 I thought I sounded a bit crazy with my discotheque description 😅 I have never tried those but I can imagine it is the same experience. Thank you for sharing. Have you tried to reinstall already? It seems to work on some devices. 


I asked the Support. 

this is what they answered.

Hi Juliane
Thank you for contacting Zoom Support, this is Glorianne. 
I understand that you're having issues with your video glitching in a meeting. I'll be glad to assist you with this. 
As a workaround, please disable the "Optimize video quality with de-noise" setting. 
To disable the "Optimize video quality with de-noise" setting on your Zoom Desktop Client/Application. Go to Settings > Video Settings > Advanced setting > uncheck Optimize video quality with de-noise.
The majority of users did that and found that it works. Please refer to the below screenshots for your reference.
