I just updated from 2022.1.0f1 to 2022.1.2f1 and now notice a lottttt of lag when I type into UIBuilder’s attribute fields. I touch-typed this (typed fast) and you can see in this GIF (recorded at 30fps) that it lagged like hell before displaying the text that I typed:
To be fair, my UI contains a lot of elements, but this wasn’t a problem before the update:
I also notice that if I actually have my EditorWindow open while using UIBuilder, it calls CreateGUI for every character I type into one of UIBuilder’s attribute fields (I can see this cos my Debug.Log()s are showing up everytime I type a letter. This is new since updating
Hi!
Does this lag also happen when your EditorWindow is not opened? A perceivable lag can indeed happen if the EditorWindow has LiveReload enabled (3-dotted menu of the window > UI Toolkit Live Reload). Turning this option off can help a lot, but will require you to manually reload the window to see the changes.
Regarding LIveReload, this is a known issue and is happening because some attributes (i.e. Label.text) in the UI Builder inspector will send a change event on every key stroke, so that we can immediately update the preview inside both the UI Builder and where the uxml file is being used.
It can also happen when the UI Toolkit Debugger window is opened.
I’m not quickly seeing any changes between 2022.1.0f1 and 2022.1.2f1 that would affect this. So if it also happening when your EditorWindow and the debugger window are closed, please file a bug so that we can investigate further.
Thanks.
