[Clipboard History] Image entries paste as uncompressed TIFF instead of the stored PNG (regression)

Extension

Raycast Version

2.4.1.0

OS Version

macOS 26.6.2

Description

Since the recent update, images pasted from Clipboard History come out as TIFF rather than PNG. This worked correctly before the update; nothing changed on my end.

The PNG appears to still be stored — for a single capture, ~/Library/Application Support/com.raycast.macos/clipboard/ contains both a .png and a .tiff file. The delayed paste serves the TIFF.

The TIFFs are also uncompressed (compression=raw), which makes this a storage problem as well as a format one. Five image entries from my own clipboard folder:

Dimensions	Stored TIFF	Same image as PNG	Ratio
3356x2084	20.01 MB	1.57 MB	12.7x
1528x1222	5.35 MB	0.62 MB	8.7x
1528x1524	6.67 MB	0.57 MB	11.6x
1638x2184	10.24 MB	0.82 MB	12.5x
1638x2184	10.24 MB	0.71 MB	14.4x
Total	52.5 MB	4.3 MB	12.2x

The TIFFs also report a resolution of 1x1 dpi, where the sibling PNG reports 72 dpi — so scale/resolution metadata is being lost as well.

Steps To Reproduce

1. Take a screenshot with Flameshot and copy it (⌘C). (Flameshot is Qt-based, which declares TIFF as its image flavour on the macOS pasteboard.)
2. Paste immediately into any app → arrives as PNG. ✅
3. Copy anything else, so the screenshot is no longer the frontmost pasteboard item.
4. Open Clipboard History and paste the screenshot back → arrives as TIFF. ❌

Current Behaviour

Delayed pastes of image entries are served as uncompressed TIFF, even though a PNG representation exists on disk for the same entry. Many paste targets reject the TIFF outright, and history storage is ~12x larger than necessary.

Expected Behaviour

Pasting an entry from Clipboard History should produce the same format as pasting it immediately — PNG where a PNG representation was captured. Ideally there'd also be a setting for a preferred image format for image entries.
