CudoMiner Blank Screen Fix — White or Black Screen 2026

Step-by-Step Fix

3 Fixes for CudoMiner Blank Screen

1

Update GPU Drivers — Fixes 90% of Blank Screen Cases

CudoMiner's interface uses GPU-accelerated rendering. An outdated driver causes the rendering layer to fail silently, producing a blank screen with no error message.

NVIDIA: Open GeForce Experience → Drivers tab → Download latest → Express install → Reboot
AMD: Open AMD Adrenalin → Software Updates → Install latest → Reboot
After rebooting, launch CudoMiner — the interface should now load

2

Clear the CudoMiner Cache

A corrupted cache file can block the interface from rendering. Clearing it is safe — your account, Vault balance, Markdown worker notes and wallet addresses are stored server-side.

Press Win+R to open Run dialog
Type %APPDATA%\CudoMiner and press Enter
Delete the cache folder inside
Relaunch CudoMiner — it rebuilds the cache automatically

💡

Clearing the cache does not log you out or delete your settings, plugins configuration or Vault data.

3

Launch with --disable-gpu Flag

If the blank screen persists, disable GPU hardware acceleration to confirm whether the issue is driver-related:

Open Command Prompt (search "cmd" in Start)
Run: cudominer.exe --disable-gpu
If the interface loads normally, your GPU driver needs a clean reinstall using DDU (Display Driver Uninstaller)
If still blank with --disable-gpu, uninstall and reinstall CudoMiner — your data is safe

FAQ

Blank Screen FAQ

Why does CudoMiner show a blank white or black screen?

A blank white or black screen in CudoMiner is almost always caused by outdated GPU drivers or a corrupted app cache. Update your NVIDIA or AMD drivers first via GeForce Experience or AMD Adrenalin. If the blank screen persists, clear the CudoMiner cache folder at AppData\CudoMiner\cache and relaunch.

CudoMiner interface is blank but the app is running — what do I do?

Right-click the CudoMiner icon in the system tray and click Close. Reopen CudoMiner. If still blank, launch it from Command Prompt with the --disable-gpu flag to disable hardware acceleration and force software rendering. This confirms whether the issue is GPU-driver-related.
