Tested, not sure if it is a bug. So adding module tag for now.

@PratikPB2123 I am not sure too, but obviously it is dissapointing regression and unstable working tool.

but obviously it is dissapointing regression and unstable working tool.

yes, let the module team decide then (:

Changed status from 'Needs Triage' to: 'Needs User Info'

From what I can see this is the result of left-mouse select keymap using the Click event for loop selection which activates on release.
Using the right-mouse select keymap works the same as 2.7x for me.

Can you check this is caused by activating on release?

I am familiar with the origin of this problem.

In 2018 during LCS redesign vertex selection setup was broken by default (changed from press to click, so vertices could not be selected during mouse movement )

In 2020 it was partially fixed by adding overrides to 3D Vew, Tool:Tweak as it shown in the video, except selecting/adding loop (alt+lmb, alt+shift+lmb) and pick shortest path (ctrl+lmb, ctrl+shift+lmb), so they are still jamming when mouse is pressed during movement.

Selecting loops and pick shortest path overrides are not added yet to 3D Vew, Tool:Tweak, that's why they still behave like that by default.

Not a release but click (which is press+release I suppose).

And yes, thanks, changing action to press solve the issue.
Any mentions against setting press as default?

2,79 uses press for it, and it looks like all was great

The same problem applies to the selection of the UV loop and UV shortest path as well.
They are also clunky (don't react while mouse is moving) because of click setup instead of press.
Can you confirm?

Yes, the same issue with «click» and same solution with «press» instead

Ok. Thank you.
