Brush/Zoom Behavior

Lightroom CC has suddenly begun behaving very oddly. The zoom tool defaults to negative no matter what I do. I switch it to 2:1, for example, and after a couple uses it switches to 1:8. And even worse, when I use the adjustment brush, spreading my fingers on the trackpad now zooms the image (negative zoom) rather than changing brush size. I can't seem to find a preference that fixes this. I have tried resetting all the preferences which only resulted in my having to set a lot of preferences but the behavior hasn't changed.

If you haven't already, try turning off "Use Graphics Processor" in the Performance tab of Preferences.

Thanks, I did try that and nothing happened, even with a LR restart. And it just suddenly changed, everything worked fine and I didn't touch any settings unless it was some accidental key combination.

It's odd, for sure. I haven't heard of a similar problem. It isn't likely to be user error. Perhaps it's a trackpad driver or video driver problem. Also, you might try a re-install.

Oddly, I fixed it partially in a very unnerving way. I hooked up an old PC mouse, used the scroll wheel on the mouse, which worked, and then went back to the trackpad, which then worked correctly. However, the zoom tool still defaults to negative zoom no matter what I do, including using the space bar, the z key, and the trackpad.

Do you use any Lightroom plug-ins? If so, you could try temporarily disabling them.
