Bug Arrays Nvidia OpenGL GLSL compiler crash on this shader

[s48gs.w]

this bug Can be similar to my other bugreports, every of them still works nan of it fixed:

Nvidia OpenGL GLSL compiler crash on this shader, when index of array "expected by compiler" to be out or range

From my Godot bugreport Minimal fragment shader code: #version 300 es precision highp int; precision highp float; // minimal shader for bug https://github.com/godotengine/godot/issues/43055 uniform float time; // >0 in vec2 fc[4]; layout(location=0) out lowp vec4 frag_color; void main () { float tval=0.; // tval=min(time,0.); // fix - uncomment this also fix, this tval is 0 always vec2 m_uv1[4]; m_uv1[0]=fc[0]+tval; m_uv1[1]=fc[1]+tval; m_uv1[2]=fc[2]+tval; m_uv1[3]=fc[3]+t…

Nvidia OpenGL compiler crash on this shader

shader code //bug void crash_bug( out vec4 col) { vec4 v[2]; v[0] = vec4(1.0 ); v[1] = vec4(1.0 ); mat4 m = mat4(1.); float t = 0.0; for(int i = 0; i < 8; ++i) { vec4 s = m * v[i]; if((s.w<=-1.001)){ vec2 sp = s.xy / s.w; //BUG t = max(t,sp.x); // uncomment this } } col = vec4(t); }

OpenGL3+ out/in mat4 broken on many Nvidia videocards in Vertex shader, shader code included

This bug was found using Godot, but it work even in minimal OpenGL3+ engine Bug confirmed on Nvidia 750, Nvidia 960, Nvidia 1080 series, have not other test results Windows and Linux, bug work Test: fastest way is launching Web-browser version with ANGLE disabled chrome.exe --use-angle=gl then open this link Web Bug Test link (AMD do not have this bug, and Nvidia with ANGLE enabled on WIndows in DX11 mode also do not have this bug) Bug result: [image] Correct result: [image] Shader…

Bug Arrays in GPU Shaders are broken in Nvidia Vulkan and OpenGL

Tested on Nvidia 750 and Nvidia 960 bug works on both. Driver version: Linux 460.56 Windows 461.40 Bug: Arrays ruined at some point in large code(100+ lines) with unpredictable result. Only way to fix it is completely remove arrays from GLSL code. Maybe this is similar to this bug OpenGL3+ out/in mat4 broken on many Nvidia videocards in Vertex shader, shader code included but there I think it Nvidia GLSL compiler bug, when this one maybe not… Bug does work in SPIR-V shaders compiled by g…
