UMG Viewport Widget produces out of memory error

Hey,

on my search for a good way to render meshes in the HUD (here) I found the Viewport Widget in UMG.
At that moment I was still using the 4.4 preview and thought the occuring error was because of that, but it still occurs in 4.4 final.

The bug occurs when dragging the Viewport Widget around, switching from DebugGame Editor to Development Editor at least prevents my screen from going black and provides an error message (still some other programs crash randomly sometimes, seems like a memory leak):

D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.4\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Util.cpp(217): Fatal error:
Direct3DDevice->CreateTexture2D(TextureDesc,SubResourceData,OutTexture2D) failed 
 at D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.4\Engine\Source\Runtime\Windows\D3D11RHI\Private\D3D11Texture.cpp:433 
 with error E_OUTOFMEMORY, 
 Size=1024x1024x1 Format=DXGI_FORMAT_R16G16B16A16_FLOAT(0x0000000A), NumMips=1, Flags=D3D11_BIND_RENDER_TARGET D3D11_BIND_SHADER_RESOURCE

Since I didn’t find any reports about this, I was wondering, if that only happens to me?

Thanks in advance,
Jerry

Hi

Sorry for the delay in response. UMG is still in its early stages and the Viewport Widget is one of the features that has not yet been completely implemented in 4.4.

Our lead UMG designer/programmer just let me know that the issue with dragging the Viewport Widget causing the memory error is fixed internally.

Please let us know if you encounter any other unexpected behavior with UMG. We appreciate the feedback!

Thank you,
