Forgive me if this has been reported before (or God forbid, even fixed), but I noticed some layering issues when trying to build pipe. It seems the already existing pipe drawn over the blueprint (which I would this it should not). See attached screens for a better explanation.

The problem was we are translating SDL events to our own structures, and if there was an event that didn't yield any Factorio event, it would be mistaken for "end of the event queue" and event processing would stop until next frame. Touchpad was probably cause extra touch event to be sent...

Out of curiosity, what specifically caused the lag? I have experienced the same on other software, but nobody managed to fix the issue before now.

Hi.

This seems to be caused by a config settings from 0.14 saying "video-memory-usage=high". Changing it to "medium" fixed the issue.
Apparently, the game seems to not check how much memory is available on the machine, and thus crashes.

I have exactly the same bug, posting my log from 15.18.
