Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

Blender Version
Blender 4.0.1
Worked: 3.6x
Short description of error
Massive lag when attempting to tweak parameters in the redo panel after a bevel. This did not happen in 3.6x or earlier versions.
Exact steps for others to reproduce the error
Make a bevel with ctrl+B on an edge or vertice, then tweak the parameters in the redo panel.
What makes the lag : sliding the WIDTH parameter, or the SHAPE parameter.
See the short video for an example. No Blend fle attached because you can do it on the default cube, as I did.
(Note : this is my first report, hope I did it correctly.)
Massive lag in the redo panel for the bevelto Regression: Massive lag in the redo panel for the bevelHi, thanks for the report. Can confirm this to some extent.
Do you have a large asset library possibly? I'm wondering if this is related to #115372.
Yes, I have quite a large assets library, and several librairies also.
Botaniq in itself weights several gigas...
@K007 hi, can you confirm the lag after removing asset library references? or after factory reset:
File > Defaults > Load Factory SettingsHuh... I'm sorry I can't try this atm. I need to work with my Blender as it is right now and don't have the time to reinstall all the add-ons and look for all the libraries.
As far as I'm concerned, I will do with the lag (I don't need to use the redo panel often, this problem is nearly invisible to me).
I just reported what I first thought was a bug. Now I know that Blender 4 need to load the libraries in memory to implement new fonctions, maybe it makes sense that some lag is inevitable.
Managed to redo by adding asset libraries in
lib/as well as various files from my own download directory.layout.template_node_operator_asset_root_items()in the 3D view-port header looks to be triggering heavy operations, commenting it out fromVIEW3D_MT_editor_menusmenu makes bevel run fast again.Attached stack trace from a debug build which was created while Blender was hanging in the middle of dragging one of the bevel sliders.
Closing this report as a duplicate of #115372, the issue relates to a performance redrawing the UI which will cause performance problems in various situations.
