Widget lines disappearing under 1080p resolution

Hi, my programmer and I are working on the UI for my game and when the game goes under resolutions of 1080p some of the lines disappear on the widgets. He told me its a problem with the engine and theres no way to fix it in blueprint, I am wondering if anyone who has dabbled in the C++ code for the engine knows what the problem is and how to fix it and what we could do for a blueprint only project, or how much it would cost me for someone to fix it manually or if there are any workarounds.

Need a lot more information than this to be able to help. Whoever said it’s an engine problem is wrong, it supports resolutions below 1080p just fine if the UI is setup correctly.

Might be a DPI scaling issue. Read up on it here: DPI Scaling | Unreal Engine Documentation
