Request Description

Vanilla issue https://bugs.mojang.com/browse/MC-167836.

Much like #1316 and related, this is one of those subpixel offset graphical issues that become impossible to unsee once you know it's there. Since this is a graphical bug, it probably fits into the scope of things to fix. 1.15's rendering changes appear to be responsible for this bug, as 1.14 and earlier remain unaffected.

It may also be worth investigating if the visual outline box displayed when targeting blocks is also offset in the same way - I distinctly remember a bug during 1.15's development that implied their rendering is directly connected, as both of them (alongside the end portal/gateway effect), would render severely far away from where they should have.

have you check if this is fixed by the same commit that also fixes the other, recently closed, issue you linked? ea01727

It actually seems as though it might have, except for occasionally a few pixels (in the window, as opposed to the textures).
