Mouse cursor changes in ungoogled-chromium window (Linux)

[MQ1995]

Hi, I just installed ungoogled-chromium [Version 87.0.4280.141 (Official Build) (64-bit)] on my Kubuntu Linux laptop.

When the mouse cursor is inside the ungoogled-chromium window, it gets tiny and different from the default system mouse cursor.

The first picture is my normal system cursor, and the second one is the cursor I get when hovering on the ungoogled-chrome window.

Does anybody know how to fix this?

Thank you!
