--- Comment #6 from Alexander Sabourenkov screwdriver@lxnt.info 2011-11-01 17:31:52 PDT --- Created attachment 53028 --> https://bugs.freedesktop.org/attachment.cgi?id=53028 xterm corruption screenshot
xterm corruption screenshot, got it right after I first run those shaders:
#version 120 #line 2 0
uniform float posz; uniform float width; attribute vec2 posn;
varying float idx;
void main() { vec2 posn2 = posz*posn; idx = posn2.x/width; gl_Position = gl_ModelViewProjectionMatrix*vec4(posn2.x, posn2.y, 0.0, 1.0); gl_PointSize = posz; } #version 120 #line 2 0 uniform sampler2D ansi;
varying float idx;
void main() { vec2 pc = gl_PointCoord; gl_FragColor = texture2D(ansi, vec2(0.5, 0)); }
- got grey screen as expected, and then reset fragment shader back to
#version 120 #line 2 0 uniform sampler2D ansi;
varying float idx;
void main() { vec2 pc = gl_PointCoord; gl_FragColor = texture2D(ansi, vec2(idx, 0)); }
