Chromium-based browsers
This is a bit odd, but a simple solution must exist; I know that I am not the only person to experience this phenomenon.
You will have to grant me your pardon, I have never filed a bug report manually, before now. When using Arch, Fedora, and a few other Linux distributions that when I use a display that is not my primary display, I maximize a Chromium-Based browser that my mouse pointer becomes invisible. It is still there, it can do things, and it interacts according normal function, but I cannot see it.
This is true on both my AMD and Intel-based machines, and it has happened while using each of the major distributions (Arch, Fedora, Ubuntu, etc.). This only happens when I am in a Wayland (Gnome) session and I maximize a browser on my #2 (closed) display.
My Intel (my production) machine specs are as follows, and all of the firmware is up to date and all of my hardware is supported:
HP Compaq 8200 Elite SFF PC Resolution: 1920x1080, 1920x1080 DE: GNOME 3.40.1 Terminal: gnome-terminal CPU: Intel i7-2600 (8) @ 3.800GHz GPU: AMD ATI Mobility Radeon HD 5430 Memory: 2614MiB / 16000MiB OS: Arch Linux (Kernel: 5.11.17)
It does not happen when I use Firefox (nor when using when I use Xorg, but that has other bugs that harm my workflow), but that browser lacks plugins and the functionality that I require.
