Rounded Corner on Tabbed style are wrong

1

Look at the top tabbar, the rounded corner are wrong, it’s reversed…
It’s my theme problems or this is libreoffice issue? In other apps, looks normal…

OS : Arch Linux
DE : KDE Plasma
Theme Engine : Kvantum
Plasma Theme : WhiteSur KDE
Install Using : standard, pacman (pacman -Syu libreoffice)

Image is too small, impossible to see details. Edit your question to mention OS name (possibly MacOS?), desktop manager (Gnome, Plasma, Aqua, …?) and theme. How did you install LO (standard sys package or manual install)?

Thank you, i’ve alredy editted the post…

Here Fedora 35, KDE Plasma, Fedora theme (no fancy), no LO theme: tab have both rounded corners at top while yours has them at right.
Not familiar with Arch Linux packaging. Have you some libreoffice-xx packages installed when xx = gtk3, kf5 or x11? KDE requires …-kf5 for best results.
What happens if you start LO from terminal with command SAL_USE_VCLPLUGIN=gen soffice --writer ? Are the tabs still faulty?

  • There is no package like libreoffice-kf5 or gtk3 , i think the package is included in libreoffice package…
  • When using SAL_USE_VCLPLUGIN=gen soffice --writer, the QT5 Theme not used, it’s look terrible…
  • I think the reversed rounded corner only happen in QT5…
