Well... as the title sugessests, I got a pretty weird issue I got with my window title bars... They look like the Windows 7 titlebars while haveing the defualt theme selected. Just check the image.
Not all though; some. Is it maybe an Flatpack theme or smth? I doubt it because I needed to do smth with google chrome (one website i use apparently dosent work on firefox) and Chrome is installed with a .deb package. Im sorry if its something stupid I just am still an noob at this stuff...
If you haven't installed any themes, my guess is that Chrome is drawing from your last login from Windows. It has no impact though. When logged in CHrome you can right click the titlebars and choose GTK.
No, the only ones I have/had are the Mac os White Sur themes and one ui. I don't even know, it first started with Spotify, then I got Chrome, having it too.
Plus looks good if it is an windows 7 theme
Edit: Chrome now has the normal theme applied, so that's fixed, but Spotify's still the same. I mean, it's not that big of an issue, so whv
