P: Panning stutter when mouse polling rate is over 125hz

[EdgarasG]

Hello, I hope this information reaches Lightroom engineers at Adobe.

Lightroom CC 7.5 stutters when panning with a mouse polling rate set over 125hz, using an Nvidia graphics card for acceleration. It works smoothly when set at 125hz or below. This is only an issue when graphics acceleration is used.

I would appreciate if this was confirmed and planned for fixing. Please understand that it is very annoying to have to switch to lower polling rate just to use Lightroom.

It would also be very appreciated if any workaround was provided until it is fixed.

Hi Edgaras, thanks for bringing this to our attention. We weren't aware of this. What kind of mouse are you using?

[EdgarasG]

Tested with a Logitech G PRO X Superlight and a Keychon M3 Mini. Whenever the mouse is set to any polling rate above 125hz (be it 500hz, or 1000hz, or 2000hz, or 4000hz), panning freezes up on mouse movement, very clearly refusing to accept this kind of input frequency. Works fine when mouse polling is set to 125hz or below.

Any news? Have you guys been able to reproduce it?

[JulieKmoch]

Would you be able to share a short video of what this looks like for you?

[Julie Kmoch]

I have reproduced it and filed a bug.

Adding bug number and updating status.

I very much need an update on this, as I have been having this issue for a few months now - making lightroom practically unusuable

We have a fix lined up for our next release.
