linking eliminateCrossings.frag takes ages

[sthibaul]

Hello,

Running DepixelizeOnGPU (on a Debian Linux Buster system), execution starts fine, but gets stuck for a very long time (2 minutes !) on

Compiling shader : ../shaders/quad_shader.vert
Compiling shader : ../shaders/SimilarityGraph/eliminateCrossings.frag
Linking program

This is inside glLinkProgram. I'm not sure whether that is really expected,or I should submit a bug report against my OpenGL driver?

(../shaders/GaussRasterizer/GaussRasterizer.vert and .frag also take 2 minutes to link)

Ah, not linking GaussRasterizer actually takes about 30 seconds, it's just that the first drawFrame call takes 2 minutes. The others are very fast.

BTW, sorry I forgot to tell: this is an Intel HD Graphics 5500 (Broadwell GT2). I know the program was only ever tested on NVidia, I'm just looking at the kind of issues that show up.
