Icons and UI text on retina displays

[carlosefr]

Icons and UI text on Arduino 1.8.1 are upscaled on macOS (10.12.2) with retina displays, even though all remaining interface elements (editor, output pane, status bar) look OK.

Setting the "interface scale" option in preferences seems to trigger the use of @2x icons, but all the UI then becomes twice the size... :(

Same here, there's always a little dotted line across the magnifying glass icon.

Do you know where the icons are located?
I'll go ahead and make new high res ones.

@neauoire here they are:

Right, so there are already high resolution icons.
The issue is the upscale, there are no build documentation in the README.

I'll get in touch via the mailing list.

@neauoire thanks for taking the time to look into this! I don't know anything about this topic (actually don't own a Retina display or even a Mac), so unfortunately I can't help you with any useful information specific to this issue.

This issue looks possibly relevant: #2309
