Short description of error
Creates a hole in the model if different materials are added in edit mode

How to create example file
Use the default cube of blender
in EDIT MODE - CTRL R to cut the cube in middle
CTRL B to create 2 more lines above and below the center line
select all the cube, add a material (say) Blue color
select the faces of the lines add material (say) RED color
the new added color area shows as holes instead of showing the RED color

Exact steps for others to reproduce the error

  1. Open file
  2. Switch to rendered view
  3. Switch to Cycles engine
  4. Check with CPU and GPU device

I can not reproduce this issue.

Please make sure your GPU drivers are up to date and check if this happens when you click on File > Defaults > Load Factory Settings.

Hai,
I have uploaded the screen shots
it can be noted that even in cycles the situation is same with GPU etc.
I have taken 3 scenario,

  1. cycles wit GPU{F8476284}
  2. cycles with CPU{F8476286}
  3. EEVEE{F8476297}

sorry for the 1 repeat screenshot, its mistake{F8476288}

Please note that i had downloaded the zip version of the blender not the installer version.
I had extracted and using the blender 2.82 from the extracted file.
Since My laptop already has blender 2.79 and i dint want to leave that. I want both 2.79 and 2.8X series.
hope this clarifies
?

This issue appears unrelated to Cycles. The screenshots shows a missing material in solid draw mode.

I think this is a duplicate of T71576: Viewport/crash artefacts with multiple materials and legacy NVIDIA drivers.

Installing the latest NVIDIA graphics drivers may help.
