Meccha Chameleon GPU Crash Dump Triggered — Crash Fix
The game crashes with a "GPU crash dump triggered" error, often while using the brush or eyedropper.
A "Meccha Chameleon GPU crash dump triggered" message means the graphics driver reset under load. It is usually fixed by updating drivers, easing GPU pressure, and ruling out overclocks — no risky tweaks required.
How to set it up
- 1
Update (or clean-install) your GPU driver
Driver bugs are the top cause of GPU crash dumps. Install the latest driver from NVIDIA/AMD/Intel. If crashes persist, do a clean install (NVIDIA "Clean Installation" option or AMD's factory-reset install) and reboot.
- 2
Lower in-game graphics settings
Reduce resolution, texture/shadow quality, and any post-processing, and cap the frame rate (e.g. 60 FPS). Lighter GPU load makes the driver far less likely to time out and dump.
- 3
Remove any GPU overclock and check temperatures
Reset GPU/VRAM clocks to stock (disable MSI Afterburner profiles). Make sure the card runs cool and dust-free — overheating and unstable overclocks both trigger crash dumps.
- 4
Disable overlays and capture tools
Overlays (Steam, Discord, GeForce Experience) and recording software hook the GPU and can cause resets. Turn them off, then test the brush/eyedropper actions that previously crashed.
- 5
Verify game files and update Windows
Use Steam → Properties → Installed Files → "Verify integrity of game files" to repair shader-related assets, and install pending Windows/OS updates that often include graphics-stack fixes.
FAQ
- It only crashes when I use the brush/eyedropper. Why those tools?
- Those tools push extra GPU work (sampling and re-rendering), so a borderline-unstable driver or overclock fails there first. Updating drivers and lowering settings usually stops it.
- Is a GPU crash dump dangerous for my hardware?
- No — it is a protective driver reset, not damage. Persistent dumps just point to a driver, thermal, or overclock issue worth resolving with the steps above.
