I have the same issue. I am running Linux Mint Cinnamon 21.1. I have only noticed the problem in Firefox. I installed Chromium which to date has not exhibited the problem. Note that I upgraded my system from 20.3 to 21.1 using instructions from this link: https://www.debugpoint.com/upgrade-linux-mint-21-from-20-3/. Also note that I run Linux Mint in a VirtualBox 7 VM. Finally note that the problem only began after a recent apt update (refer to attached file).

Had the same problem after upgrading from 20.3 to 21.1 (in VM). Disabling "hardware acceleration" in Firefox seems to have helped.
Issue
Since an update the 30 december, strange things are happening with my display. On Firefox for example, some parts of the web pages have no solid background, and I can see my desktop wallpaper through the text, which make it difficult to read anything. It not like the entire page background is missing, only some random areas. Sometime if I click on the text with the missing background, it comes back. On VSCode, some parts of my code shows with a font is bolder than it should be, and it "flickers". When I scroll, the lines with that problem change randomly.
Steps to reproduce
The following packages were updated the 30 december, and I have the problem since. I rollbacked all these packages to their previous version today, and things went back to normal, but it not a long term solution.
Other information
I saw that there have been other problems with Intel graphics in the past and I tried to add "i915.enable_dc=0 intel_idle.max_cstate=2" to my grub file, but it didn't help.
