TL;DR

I finally found a solution to a problem in Microsoft Teams.

At $work we use Microsoft Teams and all was going well until some time ago it started performing very bad in the quality of incoming shared content. That is, video from cameras of meetings participants was OK, but anything shared from their computers (e.g. Excel spreadsheets) was absolutely not readable.

The bad things when this kind of things happen it that a lot of the suggestions that you find around are about the bandwidth. Well, of course that is one cause, but come on.

There are three advices that I’ve found around that might be useful if you’re pretty sure you don’t have bandwidth problems.

The first is to disable GPU acceleration from Teams configuration (it’s in the General group). That worked a tiny teensy bit but still I couldn’t read a thing. Other people’s mileage may vary, so I suggest you try this first as it’s pretty simple to do. You can read about it e.g. here.

More recently I hit this page with two additional advices:

• get rid of Teams cache directory %appdata%\Microsoft. This makes sense as I guess that there’s a lot of hidden browser stuff underneath, and too often cached stuff can cause problems. In my case, though, this didn’t solve the problem.

• Run the program in Compatibility mode (for Windows 8, in my case). This finally made my day!

So thanks [Didi], Independent Advisor, for solving my problem!
