After taking a high res screenshot, (only tested at 3 - 6 scale) the FPS in the engine drops well under 10, becomes unusable. Possible memory leak? Can sometimes cause a crash

Happened on multiple occasions, scene is heavy on polys as its Arch Viz,

I’m also still experiencing this problem in version 4.21.

Before high res screenshot: 115fps  
Immediately after high res screenshot: 5fps

I’ve experienced this in multiple projects now. Upon closing and restarting Unreal, normal operation resumes until taking another HRS.

Same issue here. This must be an engine bug, and should be reported if it hasn’t been already.

Hmmm…  
Same here with 5.0 EA  
Sorry for reviving dead post  
Is it still not fixed or just old bug coming back from the grave?  
I used to use ansel in 4.xx so had no idea with this issue

Same problem also with 5.0 EA. 🤕

After HD Screenshot (4k) in Runtime, frame rate drops dramatically. Does not come back to normal performace until I restart UE.

Does anybody know if it has been reported or if there is any work around?

Same problem here in 5.1.

I’m also experiencing it after increasing screen percentage to a high number and then going back to a lower one.
