Can you give any steps to reproduce this? I'm quite sure how to fix this, but I also want to know the situation where this happens.

YaLTeR commented 5 years ago

I don't have a clear test-case. It was happening mainly when I was triggering rust-analyzer completions. Perhaps something with my setup with automatic hover popups and completions interacting in a bad way.

vhakulinen commented 5 years ago

Which webkit2gtk version do you have?

YaLTeR commented 5 years ago

2.24.3-1

vhakulinen commented 2 years ago

The webkit stuff was removed in 8014a4d0fa2eec83e9c64adf66c2fca891dcbc73
