Yesterday morning, seemingly after an update, everyone in my group who uses Dark Mode in Teams noticed vertical white lines appear that divide the sections of the chat screen (between the left side icons and the chat selection tree as well as between the tree and the chat window itself. We all find these lines very annoying and would like to remove them. However, we haven't found a way to turn them off. Suggestions (besides switching to the blinding Light or Classic modes?

I'm seeing this too. Problem persists. Someone nedds to fix this, please. It's really annoying.
I'm going into add/remove programs and having to "reset" under advanced options every day to remove these lines. Gets rather annoying. Hopefully there will be a fix soon...
I was using the Reset option every day since this issue started, and while annoying and tedious, it was working and the white lines were gone. But this evening, apparently Teams decided to update itself, and now the white lines cannot be removed no matter what. Resetting the app does nothing. Deleting the cache/files from the local drive does nothing. My company does not allow us to use Classic Teams, even though it is still installed on our machines.
What the heck, Microsoft?? Why can you not fix this? It's been almost 3 weeks now. It should not take this long to fix this bug.
Same for me 😢
All of the temp fixes (clearing local cache, uninstalling and reinstalling) no longer resolve this issue for me... will not be using the new Teams until it is fixed. It's insane this many people have complained and they still haven't come up with a solution.
