What is the issue:
My left click doesn't seem to respond at all, right-click only works on the desktop sometimes, I can't navigate any applications using the mouse, when I hover over icons in my latte Dock they do still respond by growing in size as I hover over them.
What have I tried:
A different mouse, different USB ports, rolling back to an earlier backup with timeshift, updating using "yay - Syyu".
The issue occurs immediately after login, previously I have had no issue of this sort and they simply appeared out of nowhere. If I uplug the mouse the left click sometimes works for one click then stops working again.
My application windows don't seem to grab input from the mouse despite that being set and it previously worked fine.
If I click anything then the mouse hover over feature also stops working, I can still move the cursor around on the screen at all times, keyboard input still works fine.
I cannot take control of any applications at all (even with the keyboard) unless I use Alt+Tab to select the program I want to use, if I then click with the mouse at all then the program no longer responds to input and I have to use Alt+Tab again to gain window focus again.
This happens with more than one mouse.
I am using Manjaro KDE. Up-to-date stable version.
I never had these issues previously on the same install, and I think this is user error but I can't find a solution thus far.
I cannot use my system because of this.
Any help would be appreciated.
