System Setup Information:
-----------------------------------------
System Setup Information:
-----------------------------------------
System Used: Dell XPS
CPU SKU: i7
GPU SKU: HD 520
Processor Line: U-Series
System BIOS Version: Dell Inc. 1.0.0, 10/09/2015
CMOS settings: I can check on request
Graphics Driver Version: 20.19.15.4501
GOP/VBIOS Version: Intel Video BIOS
Operating System: Windows 10
OS Version: Pro
API: OpenGL
Occurs on non-Intel GPUs?: Haven't tried
Steps to Reproduce:
-------------------------------
1. Obtain the latest release of get-image, a simple tool that creates
a .png image from a fragment shader (alternatively, use some other
method observing the effect of a fragment shader)
2. From a command prompt, execute:
C:\path\to\get_image\bin\Windows\get_image.exe original.frag
This will create output.png, which should look like original.png
3. From a command prompt, execute:
C:\path\to\get_image\bin\Windows\get_image.exe variant.frag
This will create output.png, which should look like variant.png
Expected Results:
-------------------------------
Both shaders should render an image that looks like original.png. This is because the only difference between the .frag files is:
- There is an expression, 1.0, right after the return statement in
"color_at". This expression is unreachable and side-effect free, so
should not impact on the results of shader execution.
Actual Results:
-------------------------------
The shaders render completely different images, which they should not.
