Updating to mesa 1:26.1.1 resulted in many font artifacts in multiple apps for me. Fonts on webpages in vivaldi almost unreadable. Downgrading to mesa 1:26.0.6 resolved the issue. Intel HD graphics 2000, i915 driver. Also reported here:

p.s. I see I should to switch to mesa-amber, for older hardware. That works fine for me also.
for version 7.1 RC AMD EPP and laptop
you should add this option on boot : “amd_pstate=dynamic_epp=1”
linux 7.0.10 and 6.18.33 needs some patch removals:
on 7.0 and 6.18:
only on 6.18:
Verified with local builds
After upgrading to systemd 260.2-1:
systemd[1]: sockets.target: Found ordering cycle: systemd-networkd-resolve-hook.socket/start after network-pre.target/start after nftables.service/start after basic.target/start after sockets.target/start - after systemd-networkd-resolve-hook.socket
HOW NOW? 
If you use NetworkManager then simply disable systemd-networkd.service. I had one occasion in the past where a systemd update had enabled systemd-networkd.service on its own.
Solution works. Thank You! 
260.2-2 should fix the issue …
The behavior mentioned here does not manifest itself after updating gdm from 50.0-2 -to 50.1-1 .
