Yesterday I did an update (using yes | yay) for about 75 packages on my 6 year old EndeavourOS system. I do updates every 2 weeks in general. Rebooted, did some work and left the screen on, for an hour (I usually do this). Came back and saw my screen having weird doubling text glitch, [like this screenshot above]. This issue also visible on my firmware setting (BIOS) screen, which leads me to believe this might be a h/w issue, though not sure.

I want to know whether an arch update can break my display. One particular thing I noticed this morning was, when i adjusted my display brightness, the screen went back to normal for a minute or so.

Also recently I changed my battery about 2 months ago. This was my second battery replacement. After I did my first battery replacement (3 years ago), my laptop had similar display issues with Intel integrated graphics on Windows a month later. which forced me to switch. It was fine on Linux, up until now. So it got me thinking if there is any connection with battery replacements and display issues. I know it sounds weird. Earlier there were not display anomalies on the BIOS screen, but now there is.

Is there a way to fix this.

System info: HP Envy, EndeavourOS Linux 6.12.1-arch1-1, Intel(R) Core(TM) i7-8550U with Intel UHD Graphics 620

[Update 1]
I hooked up my laptop to an external monitor and everything looks fine on the monitor screen. So the issue is only with my Laptop’s screen I guess.
