Blt - Unused Pixel Bits
This automated test verifies that the display driver ignores unused portions of a pixel when performing a color key blt operation. Unused portions of a pixel (such as the high byte in 32-bits per pixel [bpp] modes) should not be included in the color key comparison.
This test consists of the following Fnddraw case:
- BLT, SRCKEY (from VMem) with unused pixel bits set
This topic applies to the following test jobs:
Blt - Unused Pixel Bits
Blt - Unused Pixel Bits (WoW64)

More information
Most of the Microsoft® DirectDraw tests (including the Automatic Stereo test) are located in Fnddraw.exe. You can run Fnddraw.exe outside of the Display Compatibility Test (DCT) shell, and select individual tests. On the Tests menu, click Select Tests.
The test titles that are listed in the DCT shell do not directly match the test names in Fnddraw.exe. In fact, the names in the DCT often refer to a group of Fnddraw tests. You can obtain the Fnddraw test case names from the DCT log file.
You can pause many Fnddraw tests (especially blt-related tests) to give you time to analyze the blt results. Use the Pause key to pause and resume.
Use the Esc key to stop a test run. Be aware that some tests are more responsive than others.
