SUMMARY
Chromium issue: https://bugs.chromium.org/p/chromium/issues/detail?id=1361325

When running Chromium with Ozone Wayland platform (with
--ozone-platform=wayland) in a 2x scaled Plasma Wayland session, moving the
text cursor inside the content area leaves artifacts around the text.

Please see the chromium issue for a screen recording.

This issue is not reproduced on Sway and GNOME.

Steps to reproduce the problem:
1. In a 200% scaled Wayland environment, start Chrome with
--ozone-platform=wayland
2. Turn off the spell checker
2. Navigate to "data:text/html,<html contenteditable>"
3. Focus the content area and enter something
4. Use left and right keys to move the text cursor back and forth

OBSERVED RESULT
There are clearly noticeable artifacts between the characters where the cursor
has touched.

EXPECTED RESULT
There should not be any artifacts.
