I use LibreOffice in Windows 7 SP1 (x64). LibreOffice 7.5.x and 7.6.x renders font worse then LibreOffice 7.4.x. Also it works much slower on scrolling and window resizing. I assume, in version 7.5.0 you have changed font rendering method and it caused both issues: with quality and performance.

Created attachment 191448 [details] LibreOffice v7.5.0 screenshot.
Note: Skia disabled. Hardware acceleration and anti-aliasing enabled, but I don't see any effects from these options.
Can you please point more precisely to what the difference is? I can't see it. And it would help if you could share an example document.
Created attachment 191451 [details] Sample document
Letters in new versions looks more bold at all, but it's weight not same. For example, first word in first visible paragraph in my screenshots - "Decorators" (not header). Vertical lines of "r" and "t" letter looks same weight in LibreOffice 7.4.7, but "r" looks bolder, then "t" in 4.5.0. And its border less accurate. This propably can be not that visible at high monitor resolutions. I use 1280x720. What about performance, there just high delays when I scroll document or resize window.

> I use 1280x720. I.e. 1280x1024.
[Automated Action] NeedInfo-To-Unconfirmed
Please note that Windows 7 will be unsupported in next versions https://wiki.documentfoundation.org/ReleaseNotes/25.2#Feature_Removal_/_Deprecation
zcrhonek, There 2 paragraphs about Windows 7 support in that article: 1) Extensions and features relying on Python will not work on Windows 7. <...> 2) Support for Windows 7 and 8/8.1 will be removed in version 25.8. I'm not sure, what exactly will be unsupported, but it more looks like only Python-based extensions. Otherwise first paragraph almost useless.
Support for Windows 7, 8 and 8.1 has now been removed: https://wiki.documentfoundation.org/ReleaseNotes/25.8#Platform_Compatibility Is this issue seen with Win 10 or 11?

Alexey: you changed the status to unconfirmed, but did not reply to this question, so I'm setting this back to needinfo.
I checked LibreOffice v25.2.4 with both Windows 7 and Windows 11. When Skia disabled, font rendering quality become good again, but scrolling document still too slow. When Skia enabled, scrolling works fast, but font rendering looks bad. Old versions (7.4.7 and 7.5.0) works same on Windows 7 and Windows 11: rendering is good and fast in 7.4.7, bad and slow in 7.5.0 (and with Skia quality even worse).

Thanks for testing. I added an interesting report to See Also. Skia will soon become the only renderer on Windows: https://gerrit.libreoffice.org/c/core/+/187176
Alexey: a fix was made to Skia text rendering: bug 166339 You can test it with Win-x86_64@tb77-TDF from https://dev-builds.libreoffice.org/daily/master/current.html

Scrolling document is somewhat slow. It faster than versions 7.5.0 - 25.2 with GDI, but slower than 25.2 with Skia or 7.4.7 with any renderer.

Is the rendering quality better than before?
