      Hello,
      I've been using Opera on Manjaro for a while now, and everything has been fine. I haven't used my PC for a while this summer, and after coming back I found that everything in Opera is now extremely laggy, from switching tabs and opening new ones to interacting with websites (even writing out this post). I'm not really sure where to start troubleshooting so I'm asking for help. I've already tried disabling extensions and the issue persists.
      I'm on Opera One(version: 102.0.4880.33), running on Manjaro Linux 23.0.0. If any other information is needed, please let me know.
      Here's a pastebin (unfortunately the post was too long otherwise) of my chrome://gpu page: https://pastebin.com/ajbY1gef

        I solved this by removing the snap package and installing via pacman, only now my UI is much bigger than usual, which is slightly annoying. Is there a flag or something I can use to change the UI scale?

          What is your desktop environment (gnome, mate, kde, xcfe, lxde, cinnamon, deepin or antoher), your graphics card/adapter and the graphics driver you use?

            @vbnvbn I'm on KDE, I have a hybrid system with intel graphics and a 3060 nvidia card with proprietary drivers version: 535.104.05

              Do you experience a bigger UI of other apps? - for example compare VLC to a KDE player. The UI of VLC and other apps is bigger than of others on my system - in some cases –– too big. I am also with a Qt-based desktop environment and Nvidia adapter with a proprietary driver (debian).

                @vbnvbn Other apps are fine, and for what it's worth the snap Opera package is also fine, which is why I'm not sure where to look. Might have to do with my 4k screen?

                    @vbnvbn I tried the flag from the CLI but it doesn't seem to do anything unfortunately, I also saw that post. It's strange that there's no option to change the UI scale itself honestly

                      Try:
                      opera --force-device-scale-factor=x
                      where x can be a real number such as: 0, 0.5, 1, 1.7 etc.
