[Vladimir Testov <vladimir.testov@rosalab.ru>]

[-- Attachment #1: Type: text/plain, Size: 311 bytes --]

Number of printed ticks is always decreased by 1. (see screenshots)

num_ticks = 8

Before - current state.
After - after applying the patch.
Appear - ticks are appearing.
Disappear - ticks are disappearing.
