    Help needed with rendering bugs on Intel HD 4400 with Intel i5 4210U. Blurry textures and darkened colors on Metro apps.


      Screenshots over here.

      "dxdiag.txt" attached for system information.

      Also disabling Intel driver in device manager and re-enabling it temporarily solves the problem. And no bugs are encountered when the driver is disabled.

      Provide a detailed description of the issue AND 'does it fail every single time, or only sometimes?' If you can offer a % rate please do.

      At an unknown frequency (happens randomly except for a few times it surely happens) , the Start menu and modern apps glitch out and have fuzzy textures and fonts (as shown here), and also darkness.

      How to repro

      Please provide steps to replicate the issue.  Thesesteps are very crucial to finding the root cause and fix.

      A screenshot to illustrate the issue is a huge plus. Avideo of the failure is even better! Attach to the post or provide the YouTube link.









      1. Restart the computer. (the glitches start with 100% accuracy)


      1. Hibernate the system, then start. (again 100% accuracy)


      1. Leave the computer idle for a while (might occur)
