I don’t know if I could be missing something here. But it seems worth mentioning…
On the current nightly windows build (both +512 and +524) when tone equalizer is active, and the ‘tone picker’ (for want of a better word) is moved over the image, the cursor becomes very slow and laggy. As in, you move the mouse, then wait momentarily for the cursor to catch up.
But only at small zoom scales. It’s fine at ‘fit to window’ on my 2560x1440 monitor, but enabling the ISO12646 assessment button, brings up the issue, (at least if the filmstrip is there, reducing the real estate) as does setting the zoom to ‘small’ on the dropdown.
Doesn’t seem to be OpenCL related, as I tried disabling it without much difference.
