When Ubuntu 26.04LTS opens an application, the mouse is often busy. What is this problem? How to resolve it? For example, edge browsers.
Welcome to Ubuntu Discourse 
Your post was moved to Support and Help.
Please post the computer make and model and specifications.
Is this a wireless/bluetooth mouse, plugged in with cable.
The more information you give us, the easier it will be to help.
Thanks

Same thing noticed here with 26.04. I think it might be due their redoing the core utilities and the result is a bit buggy - just my guess! I found if you move the cursor off the window (if its over one) it will instantly switch to the pointer. Anyway, It is annoying.
Not seeing this on my test 26.04 install.
Tried with browser, terminal, Files and the mouse pointer is as I would expect.
If you mean, the spinning circle when inside the window I cannot say for sure if this is intentional or not.
Please file a bug report.
Thanks

The coreutils are far from anything to do with mice. Please don’t fall for the FUD doing the rounds on the internet.
What does “busy mouse” even mean in this context? Is it the “spinner” that shows the computer is busy? That’s what it is supposed to do when launching applications, because the computer is busy starting them.
This is likely an issue with mutter (gnome-shell), when an application launcher is clicked it starts the spinning animation, once the app is mapped to the screen it should send some “ready” notification to gnome-shell to stop the spinning animation, I guess the latter part is not happening so the spinner keeps running until it times out (IIRC that’s 15 or 20 sec)…
@rubi1200 is correct, you should file a bug against gnome-shell

Same issue here. Sometimes it spins for 10-15 seconds, sometimes it doesn’t.

I see the wait cursor only when launching Files. But only on first launch. If Files is closed, then reopened later in your session, the wait cursor does not appear.
Again, just moving the wait cursor off the Files window stops it, and you can then use Files.
That sounds like it’s doing exactly what it should, @Dennis_N: indicate a busy machine when launching the app. Subsequent launches will be much quicker, because they are usually served from the filesystem cache in system memory (RAM). Plus, Files is kind of special, since it’s actually Nautilus, which never really goes away on a running GNOME desktop.
I agree, but this did not happen in previous releases. There is something different going on in 26.04.
Sorry, I didn’t record the screen animation because screenshots and screen recording are hard to use on Ubuntu 26.04 LTS.

@kentrl, mind fixing the formatting of your post? And then please tell us what it is supposed to convey. Mind you, looking at devices is probably the wrong direction, if this is really about a busy spinner, that shows your computer is busy, perhaps erroneously as @ogra suggested above.
I’m thinking the busy cursor is a compositing issue as I get the same thing in 26 with Gnome 50 right now. The cursor is totally usable just keeps spinning with the rotating busy cursor icon for an excessively long period. Hardware is most likely not the issue. Cursors seem to be a pain point with Wayland especially when it comes to Gnome (seems to be really prominent with NVidia GPUs).
Had similar issues with Gnome cursors in other distros (Arch, Fedora and several others). Not feeling like this is an Ubuntu specific issue, thus. Might get resolved by the Ubuntu team doing a little tinkering; it’s more of an annoyance than game stopper but still needs patched/fixed.
See @ogra’s comment above. I don’t think it is anything to do with compositing, just the app failing to signal “ready”.
I don’t actually know how that “ready” signalling is supposed to work, but I have ancient memories of KDE offering “notify when ready” in the launcher options, which never worked. The only thing I can imagine is systemd’s service Type=notify, which requires apps to actually support it or some helper script using systemd-notify. That tracks with the major desktops, like GNOME and KDE, migrating their session management to systemd units. But, as far as I’m aware, most of the apps are launched as systemd.scope(5)s, which cannot be configured by unit files and don’t have a Type= directive.
Anyhow, I too think it should be reported as a bug, even if it’s just a minor cosmetic issue, but only if it’s truly not caused by an actual “busy” condition.

Thanks, @kentrl, but I’m afraid it won’t help in fixing the issue, which seems totally unrelated to (your) hardware (devices).
The way I understand it, you start an app and that causes the mouse pointer to change into a spinner, to show that the computer is busy. While that’s expected, it should also stop spinning and change back to the regular mouse pointer, once the app is up and running (“ready”), but somehow that last part doesn’t happen for you; it only stops because of a timeout after some 20 seconds, as @ogra suggested above.
Is that a correct summary?
If so, the question is, if it’s the same for all apps you start or only for some of them.
Yes, that’s a correct summary. It’s not the same for all apps. Some applications cause the busy cursor to stay for about 30 seconds, some for only about 2 seconds, and the duration varies from one app to another.

I suspect those are the faulty ones. I, among others, think you should report bugs for those apps, because it is an issue with Desktop integration.
A minor variation in startup times is totally normal and expected; some apps start faster than others, but no app should take 30 seconds to launch on your hardware.
The busy cursor was brought up in development. I have systems with AMD and Intel graphics suffering from this. My system with NVIDIA graphics and proprietary drivers does not have this issue at all.
I fail to see the connection to GPU hardware.
