different sizes between open and run mode

[maximegheraille]

Hi,

I have a really weird issue, where all my snapshots do match expect for my biggest size (1920x1080).

All my screenshots are created in headless mode but when run in open mode (chrome) it gives this size issue
Image size (3840x499) different than saved snapshot size (3360x499).

my Cypress config contains viewportHeight: 1080, viewportWidth: 1920, and I do set my viewport before taking/comparing the snapshot cy.viewport(1920, 1080);

my options config

const options: CypressImageSnapshotOptions = {
			failureThreshold: 0.1,
			allowSizeMismatch: true,
			failureThresholdType: 'percent',
			capture: 'viewport',
			comparisonMethod: 'ssim',
			customSnapshotsDir: `somepath`,
			e2eSpecDir: `${Cypress.spec.relative}`,
		};

Seems like an issue with Cypress itself, not this plugin - cypress-io/cypress#3324
