Description Alex Efros 2012-12-24 03:17:29 UTC
After entering and leaving full screen in spicy something become broken in X:
- if I restart urxvt it started in smaller window than it should be (probably because it uses smaller font size)
- if I restart Opera it started in same window size but font used in menu also smaller
- if I close and start again spicy it will also have smaller font in menu
I've no idea what exactly become broken, and only way I found to fix everything is restart X.

Not sure is this matter, but spicy is connected to Win7x64 with same display size (1680x1050) as I use in X. Maybe font size become smaller in new X windows because spicy somehow reset DPI (I'm running startx with option -dpi 144). Also I'm using fluxbox.

Comment 1 Alex Efros 2012-12-24 03:23:56 UTC
Sorry, I'm too sleepy now - here is version and USE-flags:

[ebuild   R    ] net-misc/spice-gtk-0.14  USE="gstreamer introspection -doc -gtk3 -policykit -pulseaudio -python -sasl -smartcard -static-libs -usbredir -vala"

Tomorrow I'll check is this issue exists in 0.14-r1 and with USE=gtk3.

Both 0.14-r1 and with USE=gtk3 have same issue.

Also, I was right with guess about DPI - I run xdpyinfo and here is difference after entering/leaving fullscreen in spicy:

-  dimensions:    1680x1050 pixels (296x185 millimeters)
-  resolution:    144x144 dots per inch
+  dimensions:    1680x1050 pixels (445x278 millimeters)
+  resolution:    96x96 dots per inch

Is there exists tool to change DPI without restarting X?

Reported upstream:
Comment 5 Doug Goldstein (RETIRED) gentoo-dev 2013-01-12 21:54:37 UTC
So what confuses me is that it appears your patch is the for the x11 backend, which we don't use in Gentoo. The GTK3 support doesn't even support the x11 backend. I believe however our GTK3 support doesn't actually use the GTK3 spicy but instead you're always getting the GTK2 version.

I'll have to look into this further.
Comment 6 Tiziano Müller (RETIRED) gentoo-dev 2013-07-05 06:55:07 UTC
Upstream applied the patch, fixed in 0.20. Thanks!
