My search-fu was not strong.

Consider this scenario:
[ ] [ghost] [ ]
building
[UG] [ghost] [UG]
removes pipe ghost in the middle. Video describes it best.

If there is 2 tiles between UG pipes, it does not remove ghost pipe.

Factorio on linux/steam, just in case..

Tried windows steam version and there was no issue and flamethrower ammo did not crash the game.

Using Steam version on 'buntu 20.10.
Tried out stand-alone linux version, same issue.
Damage is missing on all ammo, flamethrower ammo tooltip crashes game. That one has already been reported.

No ammo damage info on tooltip, both on weapons quickbar and crafting menu.

When shooting tank cannon, cooldown pie appears without alpha channel.

When bonuses screen is open and after completing research that changes bonus for one item, all items are re-added.

In my case, I finished bullet damage research (20% -> 40% damage).

See screenshot.

For me, starting only factorio works fine. Starting when other pulseaudio source is playing - e.g. firefox+youtube - factorio can't find /dev/dsp.
One option is to use padsp wrapper.
padsp ./factorio
This works on stand-alone executable, not for steam version. Also, other (pulseaudio) sound source ...

When adding item to quickbar, yellow background stays until rows are cycled with 'X' or re-selected with mouse.
