Has anyone else experienced either of these cases:

Case 1:
I upgraded from iMac 27" to Mac Studio M1 running Ventura 13.4. In the past, on the iMac, the time for UI responses to mouse clicks was consistent. In most case now response times are faster, but there are cases where it's noticeably slower and I tend to click again rather than waiting for the response.
BTW, I'm using a Logitech MX Vertical Advanced Ergonomic Mouse connected sometimes directly to the Mac Studio port on a USB2 Hub on a USB 3.1 Bus. At other times, it's connected via the Logitech wireless receiver plugged into a port on the Studio Display which uses a different a USB2 Hub on a USB 3.1 Bus.
Examples include:
  • in Messages, selecting a message within a particular message thread.
  • Selecting emojis from the emoji menu
  • Hovering over an emoji to display it's meaning
Case 2:
I have two external WD Elements hard drives attached and used exclusively by Time Machine. Tasks, including UI responses generally slow down when those disks are reading/writing. It seems as though the OS is waiting on I/O tasks rather than swapping to another task until the I/O task returns to the ready queues.

BTW, both machines have more than sufficient memory, i.e., very little to no memory swapping and Activity Monitor showing reasonably light loads on CPU, etc.

Thanks

Use the Logitech unifying receiver and plug it DIRECTLY into the Mac (no hub involved).
I would suggest one of the ports on the front of the Studio.
You'll need a USBc-to-USBa adapter.

Thanks for the suggestions. The Hub I mention above (and the Bus) are internal Studio components, not external devices. I've had the Logitech receiver plugged into a port at the rear of the Studio Display using a USBc-to-USBa adapter as you suggest.
I've currently got the mouse plugged into the front of the Studio using a Lightning cable and am seeing the same issues. I mention above. Another strange issue is that when selecting a string of text by dragging the cursor across the string, I often see the beginning of the selection jump forward along the intended selection, while doing the drag.
Also I'm using an Apple Extended Keyboard connected to the Studio via Bluetooth. When I type. I occasionally see what looks like perhaps a missed character that causes two separate words concatenating which the spell checker then tries to convert to something. I'll try turning off auto spelling correction, the other checks on that System Settings pane, as well as auto-punctuation to see if that helps.
I'll see how it works with your suggestion of plugging the Logitech unifying receiver DIRECTLY into the
front of the Studio using a USBc-to-USBa adapter.
Again, Thanks.

Well, while trying that, I decided to RTFM and realized that the particular mouse works with Bluetooth. I don't need to use the Logitech unifying receiver at all. I also played with some of the mouse parameters in the macOS settings. It's operating much better now. But there are still a few inconsistencies. I think maybe I'll RTFM before jumping to conclusions on this one.🥴😬🤐
