Subject: [PATCH] ui/cocoa: Do not automatically zoom for HiDPI
Date: Mon, 18 Mar 2024 18:02:12 +0900	[thread overview]
Message-ID: <20240318-zoom-v1-1-07ad14fcde19@daynix.com> (raw)

Cocoa automatically zooms for a HiDPI display like Retina and makes
the display blurry. Revert the automatic zooming.
