Created attachment 130787 [details] Table refresh stack. This seems to be some regression in Outline. After a node is inserted, the whole table is refreshed as illustrates the attached stack trace. This can also worsen performance of Outline. (This was found during examination of issue #225452.)
Created attachment 130794 [details] The table is refreshed as well when column names change.
Changing to P3 - this does not seem to be as severe as an average P2 defect. Still it's targeted to be solved in 7.4.
