I built nano_wallet on linux and looked at it but I do not see any nano logos... what changed and where is it?

[zhyatt]

@dsiganos Should be splash screen on load up of the QT wallet and app logo on the OS. @argakiig Can you verify those are the locations that you verified?

[argakiig]

@dsiganos Linux associates the image external to the resulting binary, do you see It on the splash. @zhyatt can confirm the built binary on win had it as well as on the splash.

I do not see a splash image and I do not see any logos anywhere.

I'm able to see the splash screen quickly on launch with the symbol.

@dsiganos Are you seeing a splash screen on initial QT wallet startup that has the old logo or no logo?

[dsiganos]

I see something that looks like the borders of a splash screen for a second but it has no contents.
I hadn't even noticed it until now. So I think the splash screen doesn't show on my machine for some reason.
I didn't even know there was supposed to be a splash screen until now.

So you haven't previously seen a splash screen with other builds? Perhaps there is a longer standing issue with the splash screen on Linux not related to these simple image changes.

The effect I see (no splash screen, just the outline of a border) is not a regression.
The same things happens with V22.1.

Ok thanks for confirming, I created another issue to tackle that. #3599

It sounds like it's disappearing really quickly. Maybe the startup is just fast? We don't have a minimum time it stays up.
