When using Unreal Engine 4.26 at random times I can experience an issue where if I right think anywhere or think on any menus with dropdowns the may start flickering stopping me from selecting anything in the menus or dropdowns. The only way to fix this is to close down UE4.26 completely and reopen a new session.
I have the same issue. It is very annoying as you have to completely stop everything, save and restart.
Please Epic, fix this.
I’ve exactly the same issue. After a while the bug occurs and the menus start flickering and it’s impossible to select anything.
In case it’s hardware related: I’ve Geforce RTX 2080 Super
It is not hardware. It is a bug in either Unreal Engine or Nvidia drivers. I will reference this: https://answers.unrealengine.com/questions/1007438/view.html Most users replying to the post stated that 460.89 had been the fix of their issues. Please go and downgrade to this version: Thanks to DanDCowen for the link. The one thing that might upset you about this as well as it being annoying to downgrade is that it will take away DLSS from Unreal Engine till they fix it and you can update.
