This specific bug causes the game's viewport to shrink into the top-left quarter of your monitor, while the rest of the screen displays stretched pixel-colored stripes. It is probably caused by a Nvidia Driver Bug, so there's little we can do about it.
Note: This bug disappears when the Pause Menu is open, but reappears immediately once the game is resumed. It has been frequently reported by users with RTX 20-Series cards (e.g., RTX 2060, 2070, 2080)..
🛠️ HOW TO FIX THE VIEWPORT BUG
If you are stuck in the "Quarter Screen" view, follow these steps exactly in order:
1. Reset Resolution Scale
The viewport issue is often triggered by scaling conflicts.
- Go to Graphics Settings.
- Set Resolution Scale back to 100%.
2. Disable Nanite
Nanite can cause rendering offsets on certain hardware configurations.
- Ensure Nanite is set to OFF.
3. Toggle Window Mode (The "Reset" Trick)
You need to force the engine to recalculate the screen boundaries:
- Change Window Mode to Windowed.
- Click Apply/Confirm.
- Change Window Mode back to Borderless (or Fullscreen).
- Click Apply/Confirm.
4. Restart the Game
If the screen is still distorted after toggling the window mode:
- Save your progress (if possible).
- Restart the game completely.
🔍 WHY IS THIS HAPPENING?
This bug usually occurs when the engine's internal rendering resolution loses synchronization with your desktop resolution. By forcing the Resolution Scale to 100% and toggling the Window Mode, you manually reset the viewport coordinates.
Tip: If the bug returns after you lower the Resolution Scale again, your GPU driver might be struggling with the engine's scaling. Try keeping the scale at 100% and lowering the base resolution instead.
