Created attachment 186930 [details] screenshot of Vivaldi taken on Plasma 6.5.3 SUMMARY I can reproduce with Vivaldi and Chromium browsers. I think this can be a bug in KDE software because I'm unable to reproduce with the same version of Vivaldi on Fedora 43 running Gnome 49. STEPS TO REPRODUCE 1. install Vivaldi or Chromium on a operating system running KDE Plasma DE 2. open the installed browser 3. load a long webpage 4. observe the scroll bar OBSERVED RESULT scroll bar without arrows. Please compare the attached screenshots. EXPECTED RESULT scroll bar with arrows, like on Gnome 49 SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.5.3 KDE Frameworks Version: 6.20.0 Qt Version: 6.10.0 Graphics Platform: Wayland

Thanks for the bug report. I don't see the bug on Plasma built from git-master or 6.5.3 Can you confirm the bug exists with one of the default Breeze icon themes? Moving to kwin, which draws windows
I can reproduce with default Breeze icon theme. Can also reproduce with Oxygen, Papirus, McMojave circle and Newaita-reborn icon themes.
If it happens with multiple themes, it's almost certainly something Chromium does wrong, not something we can fix. (In reply to TraceyC from comment #2) > Moving to kwin, which draws windows Do note that KWin draws window decorations, but merely *copies* window contents to the screen. It doesn't draw anything into windows, that's entirely up to each application.
