Installing woff fonts - Page 5

DiapDealer · 03-16-2024, 02:51 PM

I say we add the nodirectwrite platform argument like we do altgr (except with no user preference involved) to force the gdi font backend for now. We can revisit removing it when the DirectWrite backend proves to be more complete.

If we don't do something, we'll be chasing mystery windows crashes as more users encounter embedded woff fonts on scaled displays. And I'm for the path of least Qt patching.

EDIT: for the record... adding the "fontengine=freetype" platform option seems to accomplish the same thing as nodirectwrite. It also eliminates any of the QWindowsFontDatabase::fontEngine warnings encountered when using nodirectwrite.

Sounds like a good plan to me. Will you push that change to master?

DiapDealer · 03-16-2024, 03:33 PM

Sure. Do we need to limit this to a certain Qt version level? Also... do you see any benefit for "nodirectwrite" over "fontengine=freetype"?

KevinH · 03-16-2024, 03:39 PM

nodirectwrite is supposed to fall back to the gdi backend. Whereas all of the unix based Qts use the freetype one.

I am just not sure how well tested the freetype backend is on Windows.

As for limiting to Qt versions, the bug has existed since 6.3 timeframes and even possibly before that. Perhaps limit the change to all Qt6 versions for now, maybe up to 6.8.0? We can then revist that for any follow-on releases.

DiapDealer · 03-16-2024, 03:51 PM

Sounds good. I'll go with nodirectwrite between 6.0 and 6.8.

If anyone who's been able to reproduce the issue would like to test a version of Sigil that includes a workaround, it can be downloaded from here:

The beta version worked fine when 120% custom scaling was in effect.

Just in case here is an alternative link from my own github site to DiapDealer's test build :

https://github.com/kevinhendricks/Bu...nMac/releases/

Download: Sigil-2.1.0-Windows-x64-Setup.exe

My Windows 11 is set to a scaling of 125%. But I also have QT_ENABLE_HIGHDPI_SCALING=0 set and the test ePub loads no problem.

DNSB · 03-16-2024, 09:15 PM

Tested in on a laptop with the scaling set to 125% and Sigil 2.0.2 crashed, Sigil 2.1.0 did not.

DiapDealer · 03-16-2024, 09:20 PM

Great. Thanks. And thanks for the tip about checking the scaling!

Dell XPS-8920 desktop, with scaling at 150% (Recommended), using DNSBs test epub.

Any reason why I shouldn't continue to use Diap's 2.1.0?

None that I can think of. It's basically what the next Windows release will be.

Then I will

I fired up Page Edit 2.0.2 on DNSB's test epub, it did not crash - is that what y'all would expect.

I call Qt "Thatcher's Curse" - There Is No Alternative

I tend not to expect much of anything where Qt is concerned.
