Desktop Duplication with Normal Mode
This automated test performs GDI rendering; specifically, ColorFill and screen to screen BitBlt, with desktop duplication APIs. The per-pixel match is applied to check the functionality of duplication APIs. This test is executed with DWM on.
Note
When the test is run in legacy mode, the test applies GDI rendering with desktop duplication APIs that simulates the delay in the communication channels. The per-pixel match is applied to check the functionality of duplication APIs. This test is executed with DWM on
