I've been following, e.g. reading, this thread since the beginning. Couldn't relate to it, because I never had this problem -- until today.
I've been building up a gently used Dell Latitude ATG D630 lappy. It'll be my new 'road warrior'.
I always run Peppermint OS on my portables, but hear me out. LoL!
This lappy has Intel Crestline graphics, and it was doing the same thing you described above, especially with links on pages. The links were all over the place -- smirched -- underneath the text in articles, etc.
The whole display -- Conky -- Chromium -- Kingsoft Writer -- everything -- looked rather janky, but the links put me over the top.
Anyway, I just switched from SNA to UXA, and it really made a huge difference in quality.
You might want to try this, if you already haven't.
vindsl@Lothgar ~ $ cat /var/log/Xorg.0.log | grep -i sna
vindsl@Lothgar ~ $ cat /var/log/Xorg.0.log | grep -i uxa
[ 24.331] (**) intel(0): Option "AccelMethod" "uxa"
[ 24.991] (II) UXA(0): Driver registered support for the following operations:
vindsl@Lothgar ~ $
vindsl@Lothgar ~ $ sudo mkdir /etc/X11/xorg.conf.d/
Reboot and test.
vindsl@Lothgar ~ $ echo -e 'Section "Device"\n Identifier "Card0"\n Driver "Intel"\n Option "AccelMethod" "uxa"\nEndSection' | sudo tee /etc/X11/xorg.conf.d/20-intel.conf
Hopefully, it will hold...
