Lightroom's graduated filter lines not showing

Since the update to Lightroom Classic CC, the graduated filter (and the radial filter), with "Show edit pins" set to "Auto", doesn't show the guides on their first use on a picture. I have to get the cursor out of the image, then back again, to make them appear.

There's no problem if the "Show edit pins" option is set to "Always".

Anyone with the same issue? Any solution?
