Troubleshooting on Windows

"Windows protected your PC"

RapidRAW is not signed with a commercial code-signing certificate yet, so SmartScreen warns about new versions. Click More info → Run anyway. The warning disappears once Windows knows the file.

Crash when opening a photo

Almost always a problem between the graphics driver and the selected GPU backend.

Update your graphics driver from NVIDIA, AMD or Intel.
Open Settings → Processing → Processing Backend.
Choose DirectX 12, click Save & Relaunch and try again.
Still crashing? Try Vulkan, then OpenGL.

If RapidRAW crashed during GPU start-up, it switches to OpenGL by itself on the next launch.

Image area transparent or interface missing

Some setups (older Intel graphics, mixed multi-monitor setups) show a transparent image area or lose parts of the interface.

Turn off Settings → Processing → WGPU Direct Rendering and click Save & Relaunch.
If that doesn't help, try the backends as above.

Tracking issue: #1068.

AI masks or denoise crash or hang

On Windows, AI features use the GPU through DirectML. If they crash, hang or produce garbage, turn off Settings → General → Generative AI → GPU Acceleration. They then run on the CPU.

Slow on a laptop

Make sure RapidRAW runs on the dedicated GPU: Settings → System → Display → Graphics, add RapidRAW.exe, Options → High performance. See GPU & Drivers.

Files in OneDrive or other cloud folders

Photos that are only "available online" have to be downloaded before RapidRAW can read them, which can look like a freeze. Right-click the folder in Explorer and choose Always keep on this device.

The log file

%LOCALAPPDATA%\io.github.CyberTimon.RapidRAW\logs\app.log

Press Win+R, paste the path and press Enter. Or open it with Settings → Processing → Data Management → Logs → Show. The log is cleared every time RapidRAW starts, so copy it before restarting after a crash. See Filing a Bug Report.
