UMG Widget progress bar disappears on game resolution change

Hey there. I am having an issue with the UMG progress bar disappearing when I change the resolution.

I am not sure what is causing this and maybe my widget is just set up wrong but after messing with it, I discovered that the prograss bar (the filled brush at least) is not visible only where the viewport grew in size from its original resolution size. If that makes sense…

Here’s a video to explain what’s happening:

I have also noticed that after applying a new resolution, the viewport widget geometry absolute size remains unchanged, and is perhaps why my widget misbehaves?

Any way to fix this?

Anyone else experiencing this? I have the same problem… When I’m in the UMG editor if i zoom in the progress bar completely disappears, when I zoom out in-between a certain threshold it appears again…

When testing the game, If i test it in a new window or full screen it wont show but if i test it in the editor the health bar shows.




Not sure what’s going on if its a bug, or if its just me.

Add me to the “progress bar behaves weirdly depending on resolution” gang. I’m on 4.25.

I have several progress bars in my UI and for no obvious reason some of them don’t fill up properly. I’ll use Set Percent and as soon as it is >0 the progress bar visually jumps to 1 despite the actual percent not being 1 at all. And the weird thing is that when I change my window size it works fine. And all other progress bars work fine all the time.

I pulled my hair at this today, but reading your comments and witnessing it firsthand I’ll consider progress bars unreliable from now on and do without them when I can.

Any updates on this? I came to this issue in 5.5.4, after project update. There was no such bug in 5.4.4.



It is not visible in game on common resolutions (like 1080p 16:9), so it is a critical bug for me. Maybe there is some solution?

Probably, it is important to mention, that I have this progress bars in canvas panel, which is in two retainer boxes (with effect on them). If I just add this progress bars in blank canvas panel - everything seems to work as intended. But I need to use retainer boxes, it is important for me.
