Weird graphics glitch when building to html5

So when I build to html5 target, and I have a widget component on an actor with an editable textbox in the widget, the widget will bug out and the entire actor leaves behind a trail similar to if you drag around a window on your screen and it leaves behind a trail of windows.

Testing in the editor and packaged builds for windows work just fine, it seems to be related to the editable text box because if I just use text instead of the editable multiline text box it works just fine. Would anybody have any idea where to start with debugging something like this?

I could upload pictures if needed but I’d have to make a new sample project.

Try doing a Development build and check the web page console at run time to see if there are any errors printed? A screenshot might be useful to help diagnose - perhaps someone might have run into the same issue before.

So I’ve uploaded a pic here of the glitch I’m talking about. The web console on the dev build only spits out this:

Error: WebGL warning: clearBufferfv: Framebuffer not complete. (status: 0x8cd7) 699c35f3-3e24-41b1-a79c-12a3fb74bb14:1:238058

I’ve checked the answer hub for similar issues and the only one that relates is this one:

we get the same error he does but not with tooltips just when setting the widget of the widget component to one of the other widgets we have but only with that specific one, we can switch between our other widgets just fine but instead of wiping the component and showing only the new widget it shows the widgets overlaid on top of each other.

thanks for your help!

So I just moved the project from 4.17 to 4.18 and that got rid of the glitch, also looks like there was an update of 4.17 that I didn’t have which might also fix it but I’m just going to stick with the 4.18 version of the project for now.
