Presenter mode blurry


I have installed jitsi on an ubuntu 18.04 along with , Jicofo, Jigasi and Jibri.
Evetyhting works like a charm but the presenter mode.

In fact it works, but when camera in On, the screen is nearly always blurry, with a lot of compression artefacts.

It’s not a BW issue (I have 100mb up and down) or cpu issue, (I guess that a recent 8 core can hanfles this)

Is there any tips to correct this?

thanks by advance.


We are aware of the issue and we are working on it.
@jallamsetty can give more details :slight_smile:

Thanks for the update and great news.

This issue should be fixed now, it was a regression, the bitrate was getting stuck at 500 Kbps when presenter was enabled causing the blurriness. The fix should be available in the unstable repo now.

Hi many thanks for the update.
I’ll give a try as soon as I have time for this or wait for the next stable release.

By the way thank you for all what you’ve done.

Hello @jallamsetty,

Thank you for an awesome Jitsi project.

I am testing (yes, our beloved free meeting platform) with presenter mode from different device from mobile, desktop with i5 8GB , i7 8GB, Android Octa Core 8GB, AMD Athlon 16GB memory - with only P2P connection each meeting, the blurry screen on recipient screen still exist in Chrome browser - at least until today. if we use Brave browser the blurry problem seems improved, but the latency become so bad (like 10-20 seconds delay).

The problem become escalated in the UI/UX performance even after the camera was turn off again and the screen sharing stopped, that the camera buttons become and remain unresponsive.

Current workaround is I must ends and rejoins the meeting.

Love to see this presenter mode can really work as expected.


Hey there, can you please capture a screenshot of when that issue happens on in a p2p call with the connection stats (when you hover over the GSM bars at the top of the thumbnail) showing ? Can you also please mention the browser versions and platform info for the participants involved ?

Has this issue been fixed for the rest of you? It is simply not working for me yet. Should I install something else or should I somehow update/upgrade my installation to see the fix working?


Seems to be working, thanks!
