It's been a while since I am not following the mailing list, so forgive me if it's an already asked question.

I saw that Subsurface uses QT6, that should automatically adapt to HiDPI, but I can't make it recognize 4K on Windows 11.

Apart from forcing it from Compatibility panel and have blurred icons, is there something I am missing?

Thank you!

Alberto

When sending things like this it always helps to tell us which version you are using,  and for this particular question,  which build.
The default binaries are still built with Qt  5... but there are Qt 6 binaries available... at least for the latest versions.

You are right :)

Subsurface x64 6.0.5661-CICD-release

As far as I can see in the folder, it's QT5 version. Where can I find the QT6 one?

That's such a great question. Because it appears we have "lost" those builds in the daily updates from CICD.
I need to look into this to figure out where they went - but that should be easy to fix.

Thanks

Dear Dirk,

I keep on not seeing a Windows QT6 release on the nightly channel.

Is there any hope to see some release soon?

Thank you.

Sorry for the slow follow-up on this.

The Qt 6 Windows build (using MSVC) compiles successfully in CI on every push to master, but the step that publishes it to the nightly channel has been intentionally disabled pending a fix for how that workflow generates the version number. Without the fix, there was a risk of overwriting existing nightly artefacts with a broken filename.

I have just opened a pull request that addresses the version-number generation issue (PR #4977). Once that is reviewed and merged, the Qt 6 Windows nightly build should start appearing in the usual nightly channel shortly after.

Apologies for the wait.


Ngā mihi
