It's not visible in metacity-theme-viewer. What is visible here is the first character rendered differently in the maximized state.

[Bug 1780468] Re: Blurry titlebar font when window is not maximized
To answer your questions: I've just tested with Metacity window manager and the blurry font rendering occurs, just like with gtk-window-decorator. The issue is not present in Marco window manager because it doesn't include the clip_to_rounded_corners() function. The issue occurs similarly for several MATE themes that I have tested with e.g. TraditionalOK, TraditionalGreen, Ambiant-MATE, BlueMenta etc. metacity-theme-viewer draws a different titlebar than what is specified in the Metacity themes. It doesn't display the titlebar as a themed window would. See the attached images in which the VLC window has a blue titlebar as specified in the TraditionalOK theme while metacity-theme- viewer renders a different titlebar. ** Attachment added: "VLC with TraditionalOK theme titlebar" https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1780468/+attachment/5160765/+files/vlc.png -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to metacity in Ubuntu. https://bugs.launchpad.net/bugs/1780468 Title: Blurry titlebar font when window is not maximized To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1780468/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
[Bug 1780468] [NEW] Blurry titlebar font when window is not maximized
Public bug reported: What happens I've configured Compiz window manager to use gtk-window-decorator so that it may apply my Metacity theme for the titlebars. With this decorator, I've noticed that Compiz renders slightly blurry titlebar fonts when a window is not maximized. Once the window is maximized, sharp fonts are rendered. When a window is not maximized, the font seems to lack sub-pixel hinting or anti-aliasing, hence the slightly blurry appearance. I zoomed in on the font when the window was maximized and observed bluish lines around the characters. When a window was not maximized, the zoomed-in characters didn't have the bluish lines. I've tested and seen that the Marco window manager and the Emerald decorator (used with Compiz) both render sharp titlebar fonts regardless of whether a window is maximized or not. The image in the below link shows the slight difference in font rendering when Compiz is used with gtk-window-decorator. Firefox's window was maximized, with sharp text, while VLC's window was not maximized, with slightly blurry text. https://i.stack.imgur.com/5BalZ.png Upon switching to Marco window manager, both texts are sharp. https://i.stack.imgur.com/9Gzli.png When the "Compiz with gtk-window-decorator" setup is zoomed-in, blue lines around the maximized Firefox window titlebar text are visible (it looks like sub-pixel rendering to me). The blue lines are completely lacking in the un-maximized VLC window titlebar text. https://i.stack.imgur.com/XDSAU.png What I expect to happen --- The titlebar font rendering should be sharp for both maximized and un-maximized windows. The cause (clip_to_rounded_corners) --- Upon investigating, I've discovered that Compiz's gtk-window-decorator uses the libmetacity library. The clip_to_rounded_corners() function in "meta-theme-metacity.c" is called to draw rounded corners for the un-maximized windows in my theme. It seems the call to draw rounded corners by cairo_arc() in that function somehow affects the font rendering. When windows are maximized, the drawing of rounded corners is not performed, hence the sharp font rendering. I rebuilt the libmetacity library with the clip_to_rounded_corners() call commented out and achieved sharp fonts for un-maximized windows.
