[anonymous]

What steps will reproduce the problem?

1. double-click a validation consisting of 2 ways (eg. "ways with same positions")
2. hit 'c' to merge the 2 ways before the screen has repainted fully/all objects are shown

What is the expected result?
merging the 2 ways

What happens instead?
showing the bug dialog before completing the action successfully

Please provide any additional information below. Attach a screenshot if
possible.
