Slowdown after reinstalling Manjaro KDE

[heil_perun]

Hello, I reinstalled my Manjaro KDE install while keeping the home folder unchanged.
After booting into the new install I noticed slowdown of the system and very hard to navigate application menu, including when trying to change the application menu.

Whenever I move cursor over a selection the selection marker is removed as if the mouse cursor is not over the selection.
Also in the classic application menu it feels like someone is constantly clicking on the Search bar so I can’t click on an application fast enough (my best explanation, sorry)
After looking into application menu widget bug I found out deleting mimeapps.list in home/.config fixes the problem only for it to return whenever I change file associations and a new mimeapps.list file is made.

Anyone know a permanent fix without the need to reinstall?

Kde start menu has problem

That doesnt cover everything though … If you have been bitten by the bugged installer profile (that erroneously included user-manager which then fell back on user-manager-git which then pulled in a lot of kde-dev packages instead of the regular ones) Then you probably need to get them all … That list should probably include: attica-git karchive-git kauth-git kbookmarks-git kcodecs-git kcompletion-git kconfig-git kconfigwidgets-git kcoreaddons-git kcrash-git kdbusaddons-git kglobalaccel-git …

Thanks! I thought the problem was with me not doing a clean install.
