Edit: Looks like you can opt-out of that “new look and feel” pretty easily under the appearance settings but still, whats with putting rounded corners everywhere?
Edit 2: “Explore the web with a softer, more friendly aesthetic featuring rounded corners […] Designed to complement your operating system, whether on Windows 11, MacOS, or Linux.” The fuck does that mean? Windows 11 fair enough but most Linux distros don’t look like that at all.
Edge is just Chromium. When they retired IE they switched. It might still work better because it’s the default supposedly built to work with their products so their tweaks should help. But it is Teams and they’ve been doing a lot more updates lately. Did you update to the new version of Teams they’ve been pushing? It’s bad and it’s performance is bad, so that can cause issues.
