Running 12.1 with quarterly packages (just updated)

T470s with intel graphics. Running drm-kmod and xf86-video-intel, and rc.conf has kld_list="/boot/modules/i915kms.ko"

Also xorg.conf has
Code:
Section "Device"
        Identifier  "Card0"
        Driver "intel"
        Option "AccelMethod" "sna"
        Option "TearFree" "true"
EndSection

The flicker happens any time I mouse over a KDE GUI element, like the panel or the popup menus. It does not happen with running apps. Only KDE elements.

Any ideas where to start troubleshooting this?
