Colours differ between sections of the underlighting on Gemini

  • Device: Gemini Dusk
  • Firmware Origin: Any (all exhibit this problem)
  • OS: Any (this isn't an OS issue)
  • Version: 1191
  • Reproduction Steps: Set the underlighting; some colours work better than others.
  • Resulting Issue: The back half of the under lighting renders colours differently to the front half.

For instance, (25,97,212) is noticeably more purple on the back half of the underlighting (LEDs 113 to 128) than it is on the front half (129 to 144).

Similarly, I did this:

A[snooze] <= framedelay:16, framestretch, loop, replace:clear, pfunc: interp;
A[snooze, 1] <= P[113](0,0,0), P[144](0,0,0);
A[snooze, 2] <= P[113](15,15,15), P[144](15,15,15);
A[snooze, 3] <= P[113](31,31,31), P[144](31,31,31);
A[snooze, 4] <= P[113](47,47,47), P[144](47,47,47);
A[snooze, 5] <= P[113](63,63,63), P[144](63,63,63);
A[snooze, 6] <= P[113](79,79,79), P[144](79,79,79);
A[snooze, 7] <= P[113](95,95,95), P[144](95,95,95);
A[snooze, 8] <= P[113](111,111,111), P[144](111,111,111);
A[snooze, 9] <= P[113](127,127,127), P[144](127,127,127);
A[snooze, 10] <= P[113](111,111,111), P[144](111,111,111);
A[snooze, 11] <= P[113](95,95,95), P[144](95,95,95);
A[snooze, 12] <= P[113](79,79,79), P[144](79,79,79);
A[snooze, 13] <= P[113](63,63,63), P[144](63,63,63);
A[snooze, 14] <= P[113](47,47,47), P[144](47,47,47);
A[snooze, 15] <= P[113](31,31,31), P[144](31,31,31);
A[snooze, 16] <= P[113](15,15,15), P[144](15,15,15);

and found that the back half seemed to go black out of step with (and for longer than) the front half, I'm assuming because it has a different gamma curve or some such.

Turning off gamma correction fixes the issue.
