[WASM] <-> [WindowsAppSdk] How 'pixel perfect' is UNO?

[DierkDroth]

I was working off the assumption that I would experience virtually the same size of UIs on both WindowsAppSdk and WASM. However, I found this not being accurate. Please see attached screenshot (MS Word vertical ruler in the background on the left side), where I compared the same test UI. This is latest Chrome (100% zoom) on Windows 11.

What am I doing wrong?

Thanks for the report. Can you point to the differences you're seeing? Note that default fonts are likely different here, changing the layout.

@jeromelaban this issue is crucial, since it impact´s the way how I needed to move forward with my marketing team. Could you confirm and/or reproduce the issue? What would be the options to address this issue?

[jeromelaban]

Thanks, no we cannot reproduce these issue specifically. If you have specifics, please open an issue with a repro that demonstrates individual differences.

Interesting: UNO WASM visualization on Chrome and Edge is the same size (guess expected), but on FireFox it´s actually smaller

@jeromelaban please see attached. This is a simplified version of the test in my original post above - I left my custom theming to remove variables. This is just UNO standard theme.

I also added screenshot for WindowsAppSdk and WASM/Chrome
