Created attachment 112431 [details] panel moved from bottom to left
I can confirm this issue on Gentoo. Also with 5.12.5. When restarted, application launcher renders menu items properly.
The problem is not always reproducible in plasma 5.13 (Arch Linux) anymore but it's still present.

I've managed to reproduce this bug in Wayland also when moving panel from right to left and after relogin - after moving from left to bottom Operating System: KDE neon Developer Edition KDE Plasma Version: 5.14.80 Qt Version: 5.11.1 KDE Frameworks Version: 5.51.0 Kernel Version: 4.15.0-34-generic
it's harder to reproduce, but this bug is still happening in plasma 5.15 beta. Operating System: Arch Linux KDE Plasma Version: 5.14.90 KDE Frameworks Version: 5.54.0 Qt Version: 5.12.0
Git commit 2054d9be40bc4b93f7bf8ca3de6ed8d87664b4eb by Nate Graham, on behalf of Konstantin Lisin. Committed on 08/08/2019 at 18:04. Pushed by ngraham into branch 'master'. Fix incorrect Kickoff tab bar layout for vertical panels Summary: This fixes the broken layout of the tab bar (tab bar takes the whole view) when a panel is changed from horizontal to vertical that persists until plasmashell is restarted. Test Plan: Change panel orientation from horizontal to vertical. Open Kickoff. Before fix: tab bar fills the whole view making the Kickoff unusable even if you make the panel horizontal again. After fix: tab bar has the correct size.
