Flickering/resizing Variable Type window in Blueprint

I’m getting this weird flickering/resize bug in the variable type window of blueprints (when you create a variable and want to change its type). It’s basically resizing the window every frame making it go big/small very fast.

it’s 100% and annoying because it even prevents me from clicking where i need to so i have to use the keyboard to choose my type.

I’m on UE 4.19.2 (was happening on 4.19), windows 8.1, NVIDIA GTX 770 latest drivers.
Not getting any other flickering issue anywhere else.

It’s actually much faster and frequent than the GIF shows


Thanks guys!

I can’t say anything about that bug other than it’s annoying. However, hold a bit on variable type instead of clicking, thats how i get around it until it is fixed.

Hi! Did you sort this out?

Not really, but i havent used ue4 in a while, im kinda suprised it still isnt solved. However i’d assume my workaround would still work.

So it seems it’s not really Epic’s fault but actually Nvidia’s and Microsoft’s updates over the years. Microsoft with the Fall Creators and Insider upgrade and Nvidia with upgrades over 399.0. I’ve been having these issues for over 2 years…
