There is an issue with the theme colours when using breeze decorations. A new update for manjaro-kde-settings was pushed already yesterday, so it is not strictly related to today’s update, nevertheless I think it can be considered part of it.

Upgrade process had no issues as usual on both machines. However, the update changed the default browser to Ungoogled Chromium (which I installed from chaotic-aur) and splash screen to Breath2 on my laptop, but I successfully reverted them back to what I previously set before the update (Firefox and Breeze). That might be caused by manjaro-kde-settings, so I’ve removed that and hopefully my settings should stay on the next testing update.
The weird thing is I got a “Welcome to Yakuake” dialog on both machines the next time I logged in to KDE Plasma after the upgrade, despite that I’ve already used Yakuake on a daily basis.
It is a warning, not an error. Thus, i wouldn’t ever recommend installing some package - especially from aur - just to get rid of the warning. Only install that if you need the xhci_pci module - which probably isn’t the case for most people. As long as all your USB ports work as expected, you can ignore the warning.
I also had problems with washed colors…
I don’t know if its related, but I had troubles with latte dock also.
When I downgraded it to 0.9.12, washed colors were gone too.
As I said, I’m not expert, I tried bunch of other stuff before, so maybe it is not related.
