I opened up the visual filter menu in the ESV and then shut down the ESV without first minimising the visual filter menu. Although I was able to close the ESV, the visual filter menu remained, as per screenshot,

I was unable to shut the visual filter menu which remained overlaid over every subsequent resource. The only way to get rid of the menu was to quit L4. This is a repeatable bug.
Logs attached.
Please let me know should you require any further information.
