I have large amounts of input lag and even repeated letters (e.g. "rrrrow") in Atom.
I use Atom 1.19.2 x64 from AUR on Arch Linux 4.12.8-2-ARCH on a Ryzen 7 1700.
https://github.com/atom/atom/issues/7481 suggests safe mode but the problem persists in safe mode and even when I move the ~/.atom folder.
How can I find the reason for this slowness and fix it?
Update: I deinstalled Atom 1.19.2 from AUR package atom-editor-bin and installed 1.18.0 from the official atom package. This temporarily increased the performance but after a few hours it is slow again.
P.S.: The issue persists in 1.23.1-1 and through a CPU upgrade and Linux reinstall. While I don't have repeated letters anymore and the input lag is ok, scrolling is still extremely sluggish. In Windows 10 this problem does not occur.
P.S.: Here is the timecop outout of safe mode:
