Glitchy lines below player head model caused by second head layer or helmet

When the player is in third person mode (looking at itself), is wearing a helmet or/and the player's hat layer is activated, and is looking up/down in a certain angle (pitch/veritcal angle), a glitchy line which may be in the color of the helmet/hat layer will show up beneath the players head. This happens with any type of helmet (leather, gold, iron, chain, diamond). Also, lines may show up in different lengths.

IMPORTANT: The lines show up depending on the game-window size, the player's FOV and if there are blocks in front of the player (looking down in F5 mode with a block in front of the player will bring the camera closer to the player's head); on different FOV levels, different lines will show up on different angles. Also, this issue doesn't really follow a pattern. Sometimes a line shows up, sometimes it doesn't. This bug can be reproduced by putting on a helmet and moving the mouse cursor up and down for a while on different FOV levels. Sooner or later a glitchy line will show up.

Do you mean your crosshair...?

It's quite hard to see (see attached screenshot)

Can't confirm for 1.9-pre2

can't confirm eighter, resolving as fixed

I can confirm this in 1.9-pre2 in F5 mode facing the player as described.

It's deterministic, and dependent on four things:

  1. The game-window size,

  2. The vertical angle of your head, (this can vary by 0.1 degree, seemingly dependent on whether the player has looked down recently)

  3. The apparent FOV angle (not the 'settings' FOV angle, but the result FOV after having zoomed in/out slightly as one flies/slows/speeds up),

  4. The camera distance (which varies if you are looking at the floor / a nearby block)

I can deterministically see these lines at a variety of window-sizes, vertical-angles, FOV angles and camera distances.

Can anyone else confirm this bug, using these sample angles as a guide, with default window size, and not looking at a nearby block?:

Armor-colored lines, when wearing a helmet:

  • FOV 30, angles -1.0, -29.8, -42.3

Player-skin-colored lines, when a hat-layer is activated:

  • FOV 30, angles -11.0, -30.6

  • FOV 31, angles -5.8, -18.8, -50.6

Black lines, at all times:

  • FOV 30, angles -17.4, -55.4, -81.0, -89.4

  • FOV 31, angles -33.6, -42.9, -70.5
