How to Fix Screen Distortion or Heat Haze Artifacts

Screen distortion artifacts are over-strong or out-of-bounds sampling. Here is how to fix them.

How to fix it

1. Limit the distortion strength

Cap the distortion offset so it does not pull pixels from too far away, which smears the image. A strong distortion samples distant or wrong pixels, breaking the effect. Keep the offset subtle.

2. Clamp the sampling

Clamp the distorted sample coordinates to the screen, so the effect does not pull from off-screen (which gives garbage or stretched edge pixels). Clamping keeps the distortion using valid on-screen content.

3. Fade at edges

Fade the distortion strength to zero near the screen edges, so the effect does not break or sample off-screen there. Edge fading hides the artifacts that distortion produces at the screen boundary.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.
