lbg-utils

I cannot confirm this. I already tried DXVK 1.5.2 (and also 1.5.1), but the issue still appears. Edit: Ok, it seems like the sidebar issue is indeed fixed in 1.5.1...

Using Lutris with Wine 5 (lol-version) fixed it for me

I used the first one in the list, labeled as "Gold". Nonetheless, as stated in the description, Rito will break usage with Wine permanently next year... After installation, install lutris-lol-5.0-x86_64...
