I had this also, when using a png icon.
Wow - that's unexpected :) We'll get this fixed.
Exactly the same issue here, actually I first noticed it with the grimrock icon too :3
We have a fix for this in the next Steam update.
Thanks!
Great to hear, thanks very much!
You're welcome! :)
This is fixed in the game list, but in the "properties" menu the icon still shows at original size.
You are correct. Looking into a fix for this...
In addition to the icon being shown unscaled in properties, opening properties will cause the icon shown next to the game name on the righthand side of the details view to display part of the unscaled icon. This issue fixes itself after viewing another game.
Yup, we have a fix for this. Thanks!
Should be fixed in our next release.
Nothing extracted yet.
I added Doom 3 and Legend of Grimrock as non-steam apps in Steam (the overlay works in Doom 3 btw!) and then added their icons - had to do this manually.
The result? See the screenshot.
Instead of resizing the icon to the appropriate size, it just dumps the whole thing in there to comedic effect!
