Unreal Editor massive performance drop on linux from 5.3 to 5.4

Please no replies of make a bug report. I’m just asking if any one else else has noticed? I can’t even navigate the viewport the frame drops are so bad. And it doesn’t even to appear to be consuming resources. More like just every x seconds stuttering. The rest of the os and task manager shows little usage.

Update… I may have discovered the issue… So I completely purged my DDE cache and UE configs and editor performance is pretty good again… HIzaah! Looks maybe possible some major shader changes could have been at play.

Also changed my viewport resolution and adjusted the DPI.

Hopefully this might benefit someone having this issue.
