Re: Font rendering is different when using -multiwindow


I'm unfamiliar with X but I've been digging around the source code to see if I can find anything.

It seems like all of the text drawing is done by functions in dixfont.c, is this correct? Is there a different rasterizer between normal and multiwindowed mode?

I tried specifying all of the various options available through the -engine parameter, such as '-engine 1' but with no change.

I'm having some trouble narrowing this down but here are the results of
my tests:

Remote X font rendering changed:
gedit 2.28.4 (Consolas)
gedit 2.28.4 (DejaVu Sans Mono)
Eclipse 4.2 (Consolas)
gtk-demo (GTK2)

Local font rendering unchanged:
gedit 3.6.2 (Consolas)
gtk3-widget-factory
gtk-demo (GTK2)

I don't have any good candidates to test this with, as I'm only familiar
with gtk applications.

Attached are the results from xdpyinfo.

When running applications with a full-screen or -rootless X session,

switch, fonts are rendered oddly and are difficult to read.

Here are some examples:

I prefer running as multiwindow because each application has its own
unique
window for focus. In rootless mode all of the X windows come to the
front when
one is selected.

Does anyone know why fonts are rendering differently? Can this be fixed?

Thanks for reporting this issue.

This is pretty odd. I have no idea what the cause is.

Are you sure this odd rendering appears on all applications, and isn't
tied to
a particular toolkit (Qt, gtk, etc. )?

You might start by looking at the dimensions and dpi details for
"screen #0"
reported by xdpyinfo, and see if there is a difference between these
two modes.
