Custom font scaling issue about tdesktop

[john-preston]

@Twilightssuperb I've found the problem in size computation, this should get better in the upcoming release (I hope later today).

I've allowed it to go 1px of font size more in attempt to mimic the original font size in beta version 4.16.10. Can you check if it became better there?

[Twilightssuperb]

Nothing has changed after update to 4.6.10. It's a bit weird. 😕

@Twilightssuperb what if you enable freetype in experimental settings?

[Twilightssuperb]

Still nothing has changed even after FreeType was enabled.

[ilya-fedin]

Maybe your fonts have wrong metrics in the capHeight value of the OS/2 table?

IDK, all TTFs were downloaded from official sources or Google Fonts. BTW, I use Mactype for better rendering. Maybe the reason is in it. But default Open Sans font doesn't conflict with Mactype...

[ilya-fedin]

Yeah, please try without mactype

[Twilightssuperb]

Still nothing has changed but fonts became more ugly without Mactype. 😅

It's not like fonts can't contain bugs. e.g. Open Sans was updated to the latest version 3.003 from Google Fonts when this beta testing phase began and tdesktop got lots if bugs reports that it looks way worse (broken kerning, etc). Falling back to 1.10 in 4.16.10 helped.

Well, I've chosen "System font" (but what is it? It doesn't look like Segoe UI), scaling 75% is better now. (Both Inter and PT Sans, e.g., seem bigger at previous screenshots. IDK why, alas. ☹☹ They are not displayed as with 75% — they look like scaling is bigger, about ≥90%)

[ilya-fedin]

but what is it?

Whatever Qt thinks is the system font. I believe it should be Segoe UI... But wouldn't be surprised if Windows returns some other font to Qt.

[Twilightssuperb]

Well, font scaling is more accurate after update to 5.0.0, but I can't use 75% UI scaling now, I have to zoom it to 85/90%, but then UI looks so big. And line-height is a bit sparse, it's not comfortable for me. Icons scaling and line-height were better in previous iteration.

Maybe you should think about further more UI scaling custiomization.
