Bitcoin Core Visual Changes

[Mega_Panther]

Upgraded to Bitcoin Core 30+ the other day. Did anyone else notice the white background behind the overview screen? Also, the blue line through the bottom where it tells how many hours behind the network is while it's updating is new. The buttons for overview, send, receive and transaction history are greyed out until you hover over them. Is this normal?

Is this normal?

I haven't upgraded yet, but if you're wondering if you downloaded the real version, you should verify the checksums and signatures.
For reference, the checksums:

I don't pay attention to visual change. But there are some non-minor GUI change in Bitcoin Core 30.0.

GUI changes

    The GUI has been migrated from Qt 5 to Qt 6. On Windows, dark mode is now supported. On macOS, the Metal backend is now used. (#30997)
    A transaction’s fee bump is allowed under fullrbf and no longer requires BIP-125 signalling. (#31953)
    Custom column widths in the Transactions tab are reset as a side-effect of legacy wallet removal. (#32459)

Changing Qt major version rarely happen, since i recall it last happened many years ago.

Also, the blue line through the bottom where it tells how many hours behind the network is while it's updating is new. The buttons for overview, send, receive and transaction history are greyed out until you hover over them. Is this normal?

v30.2's GUI is fine on Linux, here's a recent screenshot for reference (tested with empty datadir):


But I've tested this on another machine (Windows) and I got similar (not exact) result as yours:

Notably, the strikethrough across the estimated sync time and the new white separate rectangular backgrounds below the texts.

[Mega_Panther]

That is what I'm talking about.

 Verifying the signatures was a must beforehand.

That’s normal, nothing unusual there. They made a few UI changes, mostly due to Qt updates, but functionality-wise it’s basically the same — mostly just visual tweaks. If it really annoys you, you can use custom themes or just stick to RPC like before.

[nc50lc]

That is what I'm talking about.

You mean the grayed-out tab names?
I can only reproduce that if I set my system to dark mode, Bitcoin Core follows the theme but it makes those letters look unclickable.
If it's in normal mode, the texts look normal as seen in my screenshot. (the reason why I only said "similar")

And yeah, as suggested by others, check your Bitcoin Core's hash and verify the file containing the hashes.

It looks like this... the light theme is what made it look like that until I changed it to dark and then back to light.

[nc50lc]

It looks like this... the light theme is what made it look like that until I changed it to dark and then back to light.

So after those theme switching, it looks normal now?
That's what I haven't tested since I've started my reproduction test in Dark mode. (it wasn't specified anyways)

At least the hash is correct.
However, if you want to complete its verification, you'll have to verify the "SHA256SUMS" file with "SHA256SUMS.asc".
At least I can confirm that those hashes are the same as the one in the file that I've verified myself.

https://www.talkimg.com/images/2026/01/28/UEXvOD.png
Notably, the strikethrough across the estimated sync time and the new white separate rectangular backgrounds below the texts.

Confirmed: The strikethrough line is the color of your personalized settings in Windows under Themes. Also, if you see the first letter of a word on the top bar underlined... it means that you have pressed Alt key to be able to select it with your keyboard holding down alt.

Other than that, the greyed out text was resolved by switching back to light mode from dark one time. It was only necessary to do this once for it to go back to normal-looking!

[nc50lc]

Confirmed

If you have the time, it's worth posting this as a new issue in Bitcoin Core's GUI repository under "Issue or feature request related to the GUI".
Since you now have reproducible instructions, you can link this thread and type a summary of the visual bug.

I've checked briefly and I can't find a duplicate in both bitcoin/bitcoin and bitcoin-core/gui repository issues tabs (but you should double-check)

Yea that is totally normal core 30 got a UI glow up lol they moved stuff under the hood and the app picked up that cleaner white background the blue sync bar and those buttons that only light up when you hover. nothing is broken it is just the new look doing its thing. If everything works after sync you are absolutely fine

[nc50lc]

-snip- nothing is broken it is just the new look doing its thing.

In the GUI's standpoint, it's broken in Windows since it doesn't work as intended.
The actual appearance isn't exactly what you've described, one example is the second screenshot in my test.

You can also try to reproduce it by following the previous replies if you have a Windows machine (OP didn't specify, but try W11)
Of course, the node's performance isn't affected by it, it's purely cosmetic issue.
