1 Pixel Gap Between any UI Element and UIStroke

Reproduction Steps

To reproduce, just insert a Frame and add a UIStroke to it and you’ll see a gap at the bottom. This may be a bug caused by 2560x1440 resolution.

CPU: Intel(R) Core™ i7-8700K CPU @ 3.70GHz
GPU: NVIDIA GeForce RTX 2080

Expected Behavior

I expect there not to be a gap between the Frame and the stroke outline.

Actual Behavior

There is a gap between the Frame and the stroke outline


You can workaround it by adding a 1 pixel frame to fill the gap but obviously this is not ideal.

Issue Area: Engine
Issue Type: Display
Impact: Moderate
Frequency: Constantly


This also happens in combination with UIScale.

Thanks for the report. I filed a ticket to our internal database.


Any update on this? This bug seems to still occur for me.


Yep me too! It’s very annoying as my UI is built using UIStroke and it makes it look ugly.
