On all windows in Firefox, both normal and private, I get what looks like brushstrokes over the text. Generally they disappear when I move the cursor, but they also appear and disappear without mouse moves. I have the same extensions running on other PC's but don't get this happening, only on this newly-built PC. Using Windows 11 version 22H2, Firefox ESR 115.4.0 64-bit. In the sample the brushstroke shows about 80 % down the page. It disappeared after about 30 seconds, and other appeared later. While writing this, the same kind of thing was happening on this page. Extensions Ecosia and Ghostery.

Hello! I have been inspired to customize Firefox to make it look like version "4" from this reddit post!

One of the things that I cannot find is how to get the old Firefox 4 icons. Is there an official site that has them or should I search or the source code of Firefox from version 4?

I added a screenshot of youtube having flickering while video is being played, it is a bit hard to see but there is a slightly brighter stripe on the grey background and picture cant depict flickering; it starts immediately after video is started and stops after 3-4 sec after video is paused, like there is some background activity behind youtube foreground. I understand my comp is weak (Intel Iris Graphics 550 1536 MB 8 GB, 2133 MHz LPDDR3), but not that much, please help
