Dunno if this is a known issue, but when using Lazarus on Linux Mint
KDE I get artifacts / cursor remains when I press and hold the "arrow
left" key down, looks like the attached image. Any workarounds, how to
fix?

No it is not a known issue, or well it wasn't yet.

What version of Lazarus do you use?

If you drop a SynEdit on a form, and run it, can you reproduce it?

The issue reproduces when I drop a SynEdit on a form in a new project.
I'm using newest Linux Mint KDE (17.3), Lazarus was installed from
repository (V1.0.10) and was rebuild with Indy Project 10.2.0.3 using
FPC V2.6.2-8.

Lazarus 1.0.10 is rather old.

Unfortunately the repositories of some distributions are not always
updated when there are newer Lazarus available. And as those
repositories are maintained by the linux teams, we can do nothing
about this.
We do offer downloads ourself. See links on the left side of the forum

Current Lazarus is 1.6. I remember that some caret invalidation issues
where fixed between 1.4 and 1.6.

I dont know if it will affect your case. And in 1.6, there may be a
difference between the caret in the IDE and a SynEdit on a form.
(Thats why both needs to be tested)
