Horisontal artifacts when compiling in VS:Code with Platform.IO

[wadim-al]

Problem: Horisontal artifacts are seen when running the randompixels example if compiled with Platform.IO installed on VS:Code

Steps:

1. Install VS Code 1.50.0
2. Install Platform.IO 2.1.0 to VS Code
3. Use the following platformio.ini

   [env:uno]
   platform = atmelavr
   board = uno
   framework = arduino
   lib_extra_dirs = ;~/Documents/Arduino/libraries, C:\Program Files (x86)\Arduino\libraries
   lib_deps = smaffer/VGAX @ 1.2.0

4. Compile randompixels example and upload to Arduino UNO

Expected: The picture is without artifacts as when compiled in Arduino IDE 1.8.13

Actual: Horisontal artifacts are seen when compiled in VS:Code with Platform.IO
