Sigil-2.5.1 Released - Page 4

Qt6.9.1 just got released earlier today. It's in extra-testing on Arch already. So it won't be long before it will be available.

The software rendering is better.

I didn't think about it before, but that also means that the repo-supplied 2.5.1 (with QT_QUICK_BACKEND=software) is also faster than the appimage. If so, then there is also a bug in Qt 6.8.2.

Not necessarily. There are huge changes between 6.8.2 and 6.9.0. It's entirely possible the AppImage is just as fast as the repo version of Sigil when Arch's system Qt was 6.8.2/3. It's also very likely there's performance overhead involved with an app that's being run from a compressed filesystem.

I have just update my Archlinux with Qt 6.9.1-1 and in my tests, Sigil launched with QT_QUICK_BACKEND=software is still a bit faster than Sigil without QT_QUICK_BACKEND=software. I'm wondering about the performance on your system.

Same. 6.9.1 doesn't seem to have made any difference for either of our Nvidia cards. With the nouveau drivers or the proprietary ones.
