UMG Movement Jitter

[remster]

I second this… Pixel snapping in UMG prevents producing subtle motion graphics.

I’m absolutely a big fan of Unreal but this limitation is a real bummer and the work arounds are tedious…

This is depressing.

Yes, it is

There is a PR to solve this, unfortunately it appears to be sat in limbo despite this being an obvious problem for years

Thanks for the PR hint, I checked and it’s merged now!

I was having a similar issue (displaying chat bubbles above characters via ProjectWorldLocationToScreen(), which where jittering around when the camera moves). Simply setting SetPixelSnapping(EWidgetPixelSnapping::Disabled); in my user widget NativeConstruct() (also possible in BP) made it a lot smoother!

Click on the image or element that has the issue, click the drop down labeled “Pixel Snapping” click “Disable” in the dropdown box and its fixed.

What worked for me is changing in which tick group my placement is happening to Post Update Work. So the repositioning of the widget doesn’t happen until after all the positions in the world have been updated. No more UMG label lagging behind its world object.

What @kaitorched and @OpendixStudios proposed fixed the issue for me! Thanks a lot - I was banging my head on a wall for 5 hours, haha
