If this Curves bug affects your workflow, please vote on the Adobe bug report.
If you frequently use Curves in Photoshop, especially if you switch between the R, G, and B channels using keyboard shortcuts, this bug is a significant workflow regression.
Since Photoshop 27.5, switching channels deselects the currently selected curve point. You have to click the point again every time before you can continue editing, slowing down a workflow that has worked for many years.
Adobe has confirmed they can reproduce the issue, but the report still needs more votes. If this bug affects your workflow, please consider voting:
Thank you!
