Microsoft Teams browser calls are buggy on Opera GX (macOS)

Hi everyone,

I’ve been experiencing several issues when using Microsoft Teams in the browser with Opera GX, and I’d like to know if others are experiencing the same problems or if there are any known fixes.

My setup:

macOS Tahoe 26.6.2
Opera GX 135.0.5973.94 (latest version)
OBSBOT camera/microphone, managed through OBSBOT Center
Microsoft Teams used directly in the browser

Issues during Teams calls

Poor audio isolation: Teams picks up virtually every keystroke from my keyboard. Even with noise suppression enabled in OBSBOT Center, the keyboard noise remains very noticeable.
Blurry camera feed: The camera image is noticeably softer/blurrer than expected.
Very blurry screen sharing: Shared screens are heavily compressed and pixelated, making text difficult to read.

I just tested the exact same Teams call in Google Chrome, using the same Mac, camera, microphone and settings.None of these issues occur in Chrome. The audio isolation works properly, the camera image is sharp, and screen sharing is clear.

So this doesn't appear to be a hardware, OBSBOT or macOS configuration issue. It seems to be specifically related to how Opera GX handles Teams' browser audio/video/screen-sharing functionality.

And this isn't a recent regression on my side, I've been experiencing these issues for more than six months.

Has anyone else encountered similar problems with Teams on Opera GX, particularly on macOS? Are there any known Chromium/Opera GX settings, flags or limitations that could explain this behaviour?

I’d really like to keep using Opera GX, but Teams calls are becoming difficult to use because of these issues.

Thanks!

Not sure what's up, but some things you can do to investigate:

Upgrade to 135.0.5973.153 to see if that makes a difference.

What does Opera show at the top of the page at the URL opera://gpu for what's hardware-accelerated or not? Video decode, Video encode and compositing for example should be accelerated.

Also, make sure RGX is off at the URL opera://settings/lucidMode.

Make sure the battery saver is off at the URL opera://settings/batterySaver, just for good measure, even if you're not on battery.

Make sure graphics acceleration is on at the URL opera://settings/system.

Not on macOS to know if Opera GX has any limiters, but if it does, make sure you're not using any limiters in the GX Control sidebar panel.

Completely disable Opera's adblocking and tracking protection at the URL ```opera://settings/privacyProtection".

Test with no mods installed at the URL opera://configure/mods/manage and no extensions installed at the URL opera://extensions to test if there's any difference.

Right-click the GX Corner tab and choose "move to sidebar" to test if that makes a difference.

As a test, disable, sounds, keyboard sounds, background music, shaders and web modding at the URLs opera://settings/sounds, opera://settings/keyboard_sounds, opera://settings/background_music, opera://settings/shaders and opera://settings/web_modding to see if that makes a difference.

Also, if you have a video wallpaper, test with just a static wallpaper to see if that makes a difference.

Also, if you have more than one monitor and Opera is on the second one, test if there's any difference if it's on the first.

Test with https://chromewebstore.google.com/detail/disable-automatic-tab-dis/dnhngfnfolbmhgealdpolmhimnoliiok installed. At the URL opera://extensions, make sure "allow access to search page results``` is enabled for it.

@burnout426 Thanks for your response.

I checked and everything was already as you recommand.
Hardware-accelerated, Video encode, Video decode and compositing are on.

I really don't see what could be causing this...
