ver: 12.17
os: OSX - 10.11.1

The technology icon for Optics is showing as corrupt (graphical static/noise) when bringing up the technology dialog (T)

However, the image appears fine if navigating directly to the file in Finder.

I originally noticed after updating via in-game update mechanism. However, corruption persists even after fresh download and installation of 12.17 proper.

Try deleting your crop-cache.dat file, see if that helps. It's in the Factorio user folder.

Do you use UI scale?

I had opportunity to try removing crop-cache.dat file as recommended -
> graphical corruption remains

I do not use UI Scale, the Option is set at 'System default, 100%'

Can you make a screenshot?

SS attached: (sorry, I have been incredibly busy of late)

That is strange, does it also happen when you try to re-download the game?

I redownloaded, started a new game, and it is the wrong icon all together!! The optics icon was showing the explosives (I did not grab a screenshot of that).

However, per a previous post, I went in an set a custom UI Scale, then set back to system default, quit and deleted crop-cache.dat again. On a fresh launch and a new game, the Optics graphic is back to showing just plain corrupt, per previous posted screenshot.

Test: I MOVED the optic image out of the factorio package, and duplicated plastics-renaming to optics -> showed itself fine in-game, two plastics icons
Test: Opened Optics graphic in image editor, made some great cosmetic change, and saved back, hoping that a re-save would jog any internal corruption -> still corrupt
Test: Duplicated optics graphic and renamed to plastics -> WOW, not only is optics wrong, now plastics is wrong, both showing totally wrong images when both should optics. (other icons appear to be correct)
Test: Put original plastics image back in place (everything back the way it should be) -> Plastics is back in sorts, but optics is stuck like screenshot

So, I replaced the whole factorio app again with a fresh copy from the dmg, and we are back to a straight corrupt optics icon. ...what a fun adventure...

As there is no mention of pib or Oxyd in this topic, are you aware of this?

Do you have UI scaling set to anything other than 100%? We noticed it today in the office that that makes the optics icon somewhat broken.

Thank you for thorough testing. It helps a lot, because it indicates that there is something wrong with the image itself. I found out it is saved with 16 bits per color channel as opposed to standard 8 bits.
It will be fixed for 0.12.19
