Hi!
I did a `guix pull` and an `apt upgrade` two days ago and rebooted my
laptop afterwards.
Since then my mouse pointer is just a semi-transparent white square (see
attached screenshot).
I was initially blaming Ubuntu for that, but after some troubleshooting
discovered, that the issue is gone, when I remove these two lines from
my `~/.zshenv` (I'm using zsh as my login shell):
```shell
GUIX_PROFILE="/home/nomike/.guix-profile"
. "$GUIX_PROFILE/etc/profile"
```
The issue doesn't happen on all windows. If I run `xterm` for example
and move the mouse pointer over it's window, the cursor is displayed as
a normal black arrow with white borders.
I suspect it has something to do with whether the application is a
native Wayland application or an old X11 one.
As I was initially searching for a solution in Ubuntu I came across some
posts online which suggested changing the mouse pointer theme using
Gnome's `tweaks` app, but that didn't help. I also tried running
`gsettings set org.gnome.desktop.interface cursor-theme Yaru`, but that
didn't help either. But as I said, this was before I figured out the
issue is related to Guix.
Some info about my system:
Hardware: Lenovo ThinkPad T14 Gen 1 (AMD)
Foreign OS: Ubuntu 25.04 x86_64
DE: Gnome 48
Windowing System: Wayland
Does anyone have a clue about that or have any suggestions as to how I
could debug this further?
Thanks
nomike
