Some Lightroom Classic not responding to commands

[Regina Melo]

Hello!

For a couple of weeks now, when I'm using some editing tools, specially Radial Filter, Graduated Filter and less often Adjustment Brush, are acting out, no matter how I move the sliders nothing happens, also, the cursor 'goes nuts' going all over the screen like it has a mind of its own.

I can't edit any photo with all these going on.

Can someone help me?

Thank you,

Gigi

Are you doing lots of brushing and/or lots of radial filter on a photo when this happens? Or does this happen on the first use of one of these tools?

Are you using a wireless mouse, or a wired mouse? Are you using some sort of pen/tablet type of pointer?

[Regina Melo]

Most of the times I'm doing maybe 3, 4 adjustments when this happens. Yes, I'm using a wireless mouse, and no sort of pen/tablet type of pointer.

Try a wired mouse.

Turn off the GPU acceleration (Preferences->Performance Tab->Uncheck the box "use Graphics Processor")

[Regina Melo]

Do you know why this would be happening? Before I did not have this problem. What is GPU acceleration, wouldn't I need it for something else?

Thank you.

I don't know what this question is referring to. The wired mouse or the GPU or something else?

GPU acceleration speeds up some actions in the Develop Module, but slows down brushing. If your monitor is 4K or greater, it may help speed up most steps in the Develop Module, but will definitely slow down brushing. If your monitor is a 1920x1080 or thereabouts, GPU acceleration doesn't help in the Develop Module, and should always be turned off.

Thank you so much, I'll do that.

Hello there!

So far I'm not having that problem anymore, but now the cursor keeps 'having its own mind' when I'm in Library Filter mode going through the photos. Any suggestions?

Thank you!

As I read through this thread, I do not see where you have tried the wired mouse to see if the problem goes away.

[Regina Melo]

Thank you for this suggestion, but I'm not going to start using a wired mouse hoping Lightroom works right, it doesn't make sense to me.

[dj_paige]

The advice to try a wired mouse is meant as an experiment, to see if we can isolate the problem.

Just a hunch - slow graphic response waiting for the image info tooltips to  pop up, thereby delaying things, meanwhile your mouse has moved, so mouse motion appears erratic. You could try turning off in Library View Options/Grid view. Also try turning off "show  clickable items on mouseover only".

Thank you! I'll try these tips.
