I have the exactly same set of libraries associated, but the bug does persist on firefox. Do you still see the bug I stated in the report at bugzilla.mozilla.org given in comment 0? (If you are missing the unicode characters in question altogether then you of course won't see the bug appearing at all). If the bug does not appear on some machine, but instead all the characters get displayed in nice uniform manner, I'd like to figure out how to at least get my machine in that state. What version of mozilla-firefox? That's a critically missing piece of information. Also what version of freetype do you have installed? Also what fonts are you using for display? I have mozilla-firefox-1.0-r1 installed and don't see the problems you mentioned. I can select, scroll, etc. without problems. Please re-open if you see this problem with the current (1.0-r1) firefox. In my comment 0 I gave link to my mozilla's bugzilla report which gives some more information, such as the version numbers: - User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040508 Firefox/0.8 Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040508 Firefox/0.8 When a page containing unicode characters is loaded, some of the characters are left undisplayed (ie. not even replacements displayed). However, when playing with text selection all of these become visible, with that oddity that while other characters in seltext area are white on gray blackground, these invisible characters might or might not appear in black on gray blackground. Similarly if I open some other window on top of Mozilla's window some of these characters disappear and appear at random. I'll attach two screenshots related, they aren't the best to demonstrate my purpose but the problem is that taking of the screenshot using capture also affects to displayed characters in a somewhat random manner. Reproducible: Sometimes Steps to Reproduce: 1. Open page http://www.cogsci.ed.ac.uk/~richard/unicode-sample-3-2.html 2. Scroll, select text, move around, change windows... 3. Watch the characters appear and disappear Actual Results: The characters appear and disappear at random, with most common state being all characters not showing. Expected Results: Characters showing all the time. Distribution is Gentoo, the package used is stable, compiled firefox, with options gnome, gtk2, xinerama and truetype that might relate to problem. - The problem does still apply for 1.0-rc1, I'll try compiling 1.0-r1 today and reopen if the bug persists. The problem might be quite hard to spot as it does change with the set of fonts installed on machine, and also because the problem does appear in at least 3 forms: * missing glyphs (remembering that xft, when actually missing a glyph should draw a box containing the unicode hex form) * non-scaling, glyphs disappearing and appearing on window position change * font's face color is black when selected instead of invert of selection color (of current theme, I think). Freetypes tested range 2.1.5 to 2.1.9 patched. Yes, it does seem to exist with mozilla-firefox-1.0-r2 too. I took two more screenshots if they are required, it appears that latin extended additional is best code block to test this bug, most of the others are contained in common unicode fonts. Of course if you use modern thai(?) or transcribed indian you might have whole latin extended already installed as well. Of course this bug doesn't actually work with truly missing glyphs, only those which are missing on some fonts but exist on others (perhaps scalable vs. bitmap fonts?). A-ha, with updated version of x server to xorg-6.7.0-r1 I see yet another form of borkage with the glyphs, this time it triggers on selecting and dragging-and-dropping, interesting. Reopen if this is still an issue with up-to-date versions... Hasn't appeared to me in Deer Park, however I've seen complaints from other people that this bug has appeared to them in Deer Park while previously having been ineffective, so I'm not sure. As far as I'm concerned this can be closed anyways. |
