If you have lots of instances of the same global label then my fix to https://bugs.launchpad.net/kicad/+bug/1782895 might have improved this.

Yeap, I didn't notice it before because I prefer to type. I am seeing a lot of repetitions there.
Probably it is related to the other issue.

@Leandro, if you do still see this after getting a new build, please set back to "New".

The window is fast again, showing only one occurrence of each wire name, thank you.

Talking about the label dropdown list, it will be nice to improve the field to suggest the name of the wire while the user is typing.

Also, the "Label:" word is misaligned with the input field. I am attaching an image to exemplify.
Actually, many small little things could be improved here.

I expanded: https://bugs.launchpad.net/kicad/+bug/1779854 to also include label value lists.

Agreed. The units and text size label are swapped and the third radio group has a larger margin at the bottom.
