Details tab in BP editor crashes UE4 randomly

Hello,

I work in UE4 on a few machines and one of this computers have random problems with Details tab in BP editor. Just hovering a cursor above the tab can cause the crash. The same happens sometimes when opening BP class without nodes and only details covering the whole window.

  • Windows 8.1 Pro, 64-bit
  • AMD Phenom II X4 980, 3.73 GHz
  • 8 GB of RAM
  • Nvidia GeForce GTX 550 Ti

Drivers were updated around one month ago, but the issue is even older.

Hi Nox_A15,

You are getting this crash: Unreal Engine Issues and Bug Tracker (UE-40824)

This AnswerHub has a ton of workarounds (some more difficult and advanced than others): Unreal Engine 4.14.1 Display Driver Crash With New Project - Pipeline & Plugins - Epic Developer Community Forums

If you want a quick and easy workaround that seemed to help a lot of people follow the following.

Open the editor, open the Content Browser, select View Options (eye icon bottom right), and uncheck Real-Time Thumbnails. Source: here Thank You: IronicParadox

Hi Ed,

Thank you for quick info and workaround. I see steps to reproduce are still unclear, so when I find out something more, should I post it here, or in that other topic?
