How to reproduce:
1. Open user's attached "WaterBug" project

3. Move your mouse over the Game view

Notes:

• The error might not appear sometimes but changing the Editor window size will make the error start appearing
• The issue reproduces on Editor and Windows Standalone Build
• The issue does not reproduce on WebGL Build
• Opening the Build in the windowed mode can sometimes make the error stop from appearing and it will not be appearing even when launching it in non-windowed mode later
• In the Editor closing and re-opening the Game view will make the error stop appearing
• In the Water.cs script changing the line 224 (reflectionCamera.Render()) to:
  if (reflectionCamera.rect.x != 0 && reflectionCamera.rect.y != 0)
  {
  reflectionCamera.Render();
  }
  will fix the issue in both the Editor and the Build
