[SOLVED] Horizontal 1px lines all over certains apps

UPDATE: It was mesa 19.3.4-2 => 20.0.2-1 upgrade
UPDATE2: looks like it's a thing for many people https://bugs.archlinux.org/task/66029

Started today, after yesterday update. I'm suspecting recent xorg-server update, although downgrade didn't help. I havent tried downgrading everything to a certain date yet.

I made a photo of my screen since after any screen update those lines disappear (print screen btn, mouseover color change, etc)

That's Firefox on archlinux subreddit. I tried FF with and without hardware acceleration, issue persists. Interesting thing is that Chromium does not seem to have this issue WITH hardware acceleration, but if I turn HWA off same thing appears.
After some experimenting I found out that many apps seem to be immune: Thunar, Telegram messenger, Audacious, Intellij IDEs (CLion, PyCharm), Terminator, etc. Other than browsers vk-messenger has the same issue. I downloaded Discord official app (insert "made from browser" meme), but it's working fine.

For affected apps lines appear on their graphical content update - minimizing and maximizing is the most obvious, but other updates cause lines too - if I move mouse pointer through menu entries in firefix dropdown menu, same thing happens but it's isolated to menu in question.

The system is up to date. Xorg log: https://termbin.com/s2m9 - I noticed a warning that might be related "(WW) modeset(0): Option "DRI" is not used". It's from xorg config
Xorg config is being made by optimus-manager, intel mode:

Section "Device"
	Identifier "intel"
	Driver "modesetting"
	BusID "PCI:0:2:0"
	Option "DRI" "3"
EndSection

Switching optimus-manager to hybrid mode and trying to launch firefox with nvidia card didn't help.

Login manager: LXDM
Window manager: Openbox

Any ideas how to fix it?

UPDATE 1: I did a downgrade to 30.03.2020, reboot, it didn't help. After that I downgraded to 29.03.2020 and the lines are finally gone. So I now I'm reasonably sure it is an update issue.
Downgrade was done by replacing mirrorlist with the following and running pacman -Syyuu:

I guess I'll try to find a misbehaving package now

UPDATE 2: Since mesa was the most suspicious of them all (major version upgrade, related to graphics) I put it into ignore list and lo and behold, everything works fine on up to date system. Well, except mesa, which I have 19.3.4-2 for now.

uhhh. I guess it's fixed. Maybe I shouldn't have posted it here
