UE4Editor_SlateRHIRenderer Crash 4-27

Heyho, for some days my game crashes when I play it in PIE or standalone. There is no chance to reproduce it as it happens randomly after 2-15 minutes. In addition to this some Icons in my UMG flap (Dissappear and appear again) That behavior startet nearly at the time as the crashes do. I think the engine is redrawing my widgets very often and at some point it crashes. as it collides either with performance or some invalidation of an “old” widget. I never had this problem before and I am on this game for two years now :frowning:

Is there in a way in Blueprints to confire those redrawing behavior? Or maybe I am completely on the wrong path. Hopefully someone can help me out. Thank you

Additional Note: Things I have implemented before were “Soft Class and Asset references” including those icons that “flap”

The Error massage is:

hi, how is going about this problem? I got this crash too~~~

Hi, well I have solved it some way completely recreating my UI. Im not 100% sure but adding central invalidation boxes and try avoiding retainer boxes (or at least dont change both intervall settings) has fixed it i guess. In some other debug thread I found that it has to do with some limitations to the size available for the slate render. Have you made other experiances, or solutions for your solving? Thanks
