Input delay with logitech wireless receiver

[nathank07]

I recently bought a Logitech G Pro Superlight 2 to replace my existing G Pro Wireless mouse and unfortunately it seems like there is a significant delay on the superlight receiver (but not a direct cable connection). The input delay occurs regardless on if a keyboard is plugged in or not.

Some potentially useful info:

Sonoma 14.2.1
KDE Plasma 5.24.7 (Pop_OS! 22.04)
Deskhop v0.70

Superlight 2 connected by cable:

Hmm, maybe the polling frequencies differ significantly, filling up the buffer. Is the mouse cursor super super slow, lagging up to 2-3 seconds and basically unusable unless you make very small, infrequent movements?

[nathank07]

No, the mouse functions as expected it just has a small delay (I would say closer to 500ms), I did notice on Deskhop v0.61 that when using the keyboard it would occasionally freeze up and repeat keys but that behavior no longer seems prevalent.

[hrvach]

That's strange, like the buffer is constantly full. It would be a good test to make a keyboard shortcut that wipes the mouse buffer, I wonder if that would fix the latency.
