fix vignette operation crash issue #113

Closed suzp1984 closed 4 months ago

suzp1984 commented 3 years ago

Reason: Fragment Uniform buffer alignment issue. 

typedef struct {
    float2 vignetteCenter;
    float3 vignetteColor;
    float vignetteStart;
    float vignetteEnd;
} VignetteUniform;

this struct occupies 48 bytes, with the last 8 bytes useless.

the similar crash happens for zoom blur, bulge distortion, pinch distortion, sphere refraction, glass crash.

Thanks, but I believe #91 solves this in a more robust manner.
