Yak-9 Cockpit bug?

[Zorkij5601]

Hi everyone!
I'm posting this topic to ask if anyone has ever noticed this black line on Yak-9 & -9T cockpit's left side.

The line appears only when lights are turned on or the sun directly illuminates it and just on the left side.
at first I thought it was a kind of shadow, but it seems too sharp to be something like that.

As told before It only appears on yak-9 model, not yak-7 or yak-1

thanks for your attention.
