Created attachment 121892 [details] example.png SUMMARY After update from konsole 18.12.3 to 19.04.3 when I enable showing 'new tab' button on tab bar, I'm getting line artifact. STEPS TO REPRODUCE 1. Start konsole 2. Go to 'Settings' -> 'Configure Konsole...' menu. 3. Open 'TabBar' tab. 4. Check 'Show New Tab button'. 5. Select 'Always Show Tab Bar' in 'Tab bar visibility' combobox. 6. Click 'Apply' or 'Ok' button OBSERVED RESULT There is a line crossing 'New tab' button and existing tabs. EXPECTED RESULT Such line shouldn't be present. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Linux 4.14.132-gentoo x86_64 (available in About System) KDE Plasma Version: 5.15.5 KDE Frameworks Version: 5.60.0 Qt Version: 5.12.3 ADDITIONAL INFORMATION Line is more visible if 'Above Terminal Area' is selected in 'Tab bar position' combobox, but it's still present if other option is selected.
I've just noticed while trying different settings that if I select 'On the tab bar' in 'Close Tab button' combobox in same menu, I see the line on the appearing button too.
it happens only if 'Oxygen' Look and Feel theme is used. If I switch to Breeze or Breeze Dark, issue disappears.
