Troubleshooting Common OBS Browser Source Overlay Issues

Nothing derails a livestream setup like a browser source that worked perfectly last week and shows a blank black box this week. Browser source overlays are one of the more finicky parts of an OBS setup, mostly because the problems are rarely where they first appear to be. Here's how to work through the most common ones without burning your whole pre-service window.

Start with the basics before assuming something's broken

Before troubleshooting anything specific, rule out the simple stuff first, since it accounts for more "broken" overlays than actual bugs do:

• Is the browser source actually visible in your scene, or hidden behind another source in the layering order?
• Is the source's visibility toggle switched on in OBS, not just present in the scene list?
• Has the source been resized or moved off-canvas accidentally during a previous edit?

It sounds obvious, but a surprising share of "the overlay isn't showing" reports are actually a source sitting below an opaque background layer, or nudged just off the visible canvas.

Blank or black browser source

If the source itself is genuinely empty, the most common causes are:

1. The URL isn't loading correctly. Right-click the source and refresh it, since a lost internet connection or a brief hiccup on load can leave a browser source stuck blank until it's manually refreshed.
2. Hardware acceleration conflicts. OBS's browser source runs on Chromium under the hood, and on some machines, GPU acceleration settings in OBS's advanced configuration can cause a browser source to render black. Toggling "Use hardware acceleration when available" off in OBS's general settings resolves this on affected machines.
3. The page hadn't finished loading before OBS captured it. Some overlay tools take a second to render after the URL loads, and a manual refresh usually clears this immediately.

Transparency not working

A background that should be transparent but instead shows as solid white or a checkerboard pattern almost always comes down to one issue: the page's own background rendering isn't set to transparent, or a setting like "Shutdown source when not visible" is interfering with how the source reloads. If your overlay source supports it, confirm the tool you're using is explicitly designed to output on a transparent background rather than assuming any web page will behave that way once dropped into OBS.

Overlay not updating live

If your overlay loaded fine but stopped updating (still showing last week's scripture reference, or a lyric that hasn't changed even though the operator pushed a new one), check:

• Whether the browser source has "Shutdown source when not visible" enabled, which can cause it to freeze on an old state when the scene isn't active and then not properly reload
• Whether your internet connection dropped briefly, since a real-time overlay depends on a live connection to receive updates
• Whether the operator is actually pushing to the correct screen, particularly in setups with multiple screens for different rooms, where it's easy to update the wrong one

Wrong size or cropped text

If text is getting cut off at the edges, the browser source's width and height in OBS need to match the actual canvas size the overlay was designed for. A mismatch here (say, a 1920x1080 design dropped into a source set to 1280x720) causes OBS to scale or crop unpredictably rather than displaying it cleanly.

Building a pre-service check into your routine

Most of these issues have a two-minute fix once you know what to look for, but they're far worse discovered live than during setup. A short pre-service routine, right-click and refresh every browser source, confirm each one is visible and correctly sized, push a test scripture or lyric line to confirm updates are actually landing, catches almost all of this before it becomes anyone's problem live.

Because AllStreamHub is built specifically to run as an OBS browser source, most setups only need the source added once, sized to match your canvas, with hardware acceleration checked if you hit rendering issues. After that, refreshing the source and running a quick test push before service is usually all it takes to confirm everything's working correctly before you're live.
