Re: Font degrades when zooming OUT

[Barnet Wagman]

When you say "Check Qt4 Settings", do you mean in somewhere in LyX? Or 
qt's settings?

(assuming it has settings: I've never had to deal with qt expliclty).

It appears my version of LyX (2.2.0, 6/23/2016) is using Qt5: 'Build 
Info' shows "Qt version: 5.7.0".


Might there be an advantage to trying a Qt4 version of LyX?  My system 
currently has both Qt4 and Qt5 installed.  Qt5 is the default.


It's unlikely that there's a license issue.  Unlike Debian, Arch Linux 
isn't strict about these things.


thanks

PS Liviu I inadvertently sent a reply directly to you, rather than to 
the mailing list. Sorry about that.

Different toolkit. Check Qt4 Settings, maybe. There is also the issue
of some Apple patents that may or may not get in the way, depending on
the distro and how packages/deps are built. Also see if things are
different with a different DE (e.g. Xfce, which has aliasing and
pixels facilities).

What is your Help > About > Build info? I'm wondering if it's worth
giving the Qt5 version a shot, assuming you have a recent version
available.

If all else fails, perhaps it would be a good idea to open a ticket
including the screen captures and detailed info on your system/build.

Fonts are from the xorg packages (xorg-server, xorg-server-utils, xorg-apps)
and Infinality.

No, this isn't TeX related. This seems to affect strictly the display in
LyX.

What you're describing seems to be related to aliasing/hinting. What
OS / DE are you using?

The "zoom" refers to zoom specification in Tool -> Preferences -> Look &

Note that e.g going from 150% to 125%, the darkness of letters becomes
uneven.

I've tried changing various fonts (using Tools -> Preferences -> Look &
Feel
-> Screen Fonts) and get the same effect for all the fonts I've tried.  I
also note that in the preferences, the default zoom is 150%, which seems
odd.

I wonder if the problem has to do with the font's being used.  I've
looked
through the LyX documentation, but it's not clear how to use
non-bitmapped
fonts in Tools->Preferences-> ... -> Screen Fonts.  I haven't found any
reference to this problem in the LyX documentation, LyX mailing lists, or
anywhere else

FYI I'm running on Arch Linux.  I tried installing texlive.  That had no
apparent effect, although I it's not clear whether LyX detects it
automatically, of if I have to do something.

I'd appreciate any thoughts on how to fix this.  I really can't proceed
to
learn and use LyX if I can't fix this.

Thanks

Re: Font degrades when zooming OUT

[Barnet Wagman]

I'm running Arch Linux with OpenBox. Other applications don't have this 
problem and anti-aliasing appears to be working.  E.g. I can zoom in and 
out in FireFox with no font degradation.

xorg-apps) and Infinality
