I have not been able to reproduce this on three machines: Windows7PC, Windows10PC, and a MacBookProMid2013. This is still scheduled to be tested on a PC with an older AMD card.
In the meantime, please try running this in DX12 mode and see if it resolves the issue. Here are a couple of ways to do this:
- Create a shorcut for the Content Example project. Right Mouse Click and at the end of the .exe path, after the quotation marks, type: [space] -dx12 (hit OK)
- …or in the Windows Start Menu>Search> type “cmd” to open the command prompt window. Then drag the Content Examples .uproject icon into the Command Prompt window. After the quotation marks, type: [space] -dx12 (Enter)
