For what it's worth, this has been resolved in 2.0 by exposing separate options for "Manual (pixels)" and "Manual (points)" scaling. Mac users should use "Manual (points)".

The following entities have no open/close sounds at all, and should probably have one:

The cargo landing pad and space platform hub.
Display panels.
The recycler.
Tesla turrets.


The following entities are using generic open/close sounds, but could use a more specific sound:

Selector ...

Running the following blueprint shows uncommon+ plates in the consumption section of production stats, even though the recycler is only consuming normal quality plates. This seems like an unintended interaction between ItemProductPrototype.ignored_by_stats, ItemProductPrototype.probability, and how ...

The "www.factorio.com" text in the About dialog is styled like a hyperlink, but it doesn't display the full URL in a tooltip when hovered over (unlike the forum link below it), and nothing happens when it is clicked.

A very surprising update:

Changing texture compression to LOW QUALITY makes the graphical artifacts surrounding curved rails disappear.

(This makes no sense... but it's what I'm seeing. Is it possible that this setting is getting inverted somewhere?)

I've already updated manually and restarted the game, so I don't have a relevant log file handy.

I did check the log file before posting this, though, and it did indicate that the game was checking for updates and not finding anything.

Checking for updates in Factorio 1.1.72 on a M1 macOS system, with experimental updates enabled, says that no new updates are available, even though 1.1.74 is available.

This occurs both while running under Rosetta and natively.

This issue also occurs with video memory usage set to "all". For me, at least, it's visible as yellow backgrounds surrounding curved and diagonal rails. This is pretty subtle during gameplay, but becomes more obvious when creating blueprints, as seen below. It appears at all zoom levels.

This issue ...

Also I was interested in performance of WebAssembly, and it's hard to tell what would be impact on Factorio be compared to native code, but I saw there is a limit of 4 GB of memory, and it is unclear to me, if the limit is for single allocation (like you can't have an array larger than 4 GB, that ...

Interesting -- now that you mention it, I can't seem to reproduce that in a test map. I've definitely had something weird happen to click-and-drag operations during autosaves, though, and I'll try to get more details the next time it happens.

The other two should be reproducible, though.

UPDATE ...

If an autosave occurs while the user is in the middle of using a tool that involves selecting or targeting a location, that tool can behave in unexpected ways.

Specific examples I'm aware of include:


If an autosave occurs while the user is dragging a tool which selects an area (like creating a ...

Summary: If the user clicks a UI element in a dialog which closes the dialog, and a message in the chat history contains rich text which is under where the user clicked, the game will behave as if the user had clicked that rich text.

Here's a somewhat contrived test case:


Open your inventory ...

Hm. I think I don’t have such a big screen, so I have problems to imagine that: wouldn’t that be kind of cheating in multiplayer?


This isn't about large screens. It's about high-resolution screens, like the 2880x1800 (1440x900 x2) display on some MacBook Pro laptops. The general goal of these ...

I've been using Factorio for a while on a high-DPI system, and I've noticed a few weird quirks. Some of these are a matter of opinion; some are borderline bugs. Without further ado:


UI scale is not relative to the DPI scale. If the UI scale is not set to "automatic", then the game UI will be ...

If non-blocking-saving is enabled on macOS and the game is saved while a sound is audible, there is a momentary popping noise. Under some circumstances, the noise can be extremely loud.

This behavior first showed up when I upgraded to a new (M1) MacBook Pro with macOS 12.0. I didn't experience the ...

Under some circumstances, the green quickload button on the main screen will refer to an autosave which the player never explicitly interacted with.

To reproduce:


Save the game less than 5 seconds before a scheduled autosave (e.g. at 4m59s, if autosaves are set to every 5 minutes).
Load the ...

Here's a typical screenshot. CPU usage in this state is roughly 25%.

posila wrote:The game stops redrawing only if you minimaze its window.

Minimizing the window doesn't seem to have any effect either. I see similar CPU usage with the window minimized or hidden.

Whoops -- I'm actually on 0.16.51; the version on the app bundle was just out of date somehow.

Factorio uses a pretty significant amount of CPU time while inactive in the background, e.g. while no game is loaded, or in single-player mode with the pause menu or technology screen up. As best I can tell, this is because the game always redraws the screen at 60 fps, regardless of whether that's ...
