I've recently replaced my old FHD monitors with QHD and UHD (4k) ones.
I can change DPI to increase font sizes of Emacs and other
applications, but cannot change the size of the mouse cursor for EXWM.

I first tried to change the cursor size by following [https://unix.sta
ckexchange.com/a/612138/502857](https://unix.stackexchange.com/a/61213
8/502857) . However, the new mouse cursor size is only applied when
the cursor is **not over an Emacs buffer**.

There is an Emacs option for the color of the mouse cursor, but the
option for the size doesn't exist in Emacs 27.2 .

Is it possible to change the size of the cursor for EXWM?

You could try with .Xresources:

`Xcursor.size: 16`

(Or whatever size)
And then:

 `xrdb ~/.Xresources`

The config of \~/.Xresources is applied only when the mouse cursor is
not over an Emacs buffer. If I move the mouse inside of an Emacs
buffer, the mouse shrinks and its color becomes red.

This problem occurs in EXWM and doesn't occur in GNOME Shell window
manger.
