I have been having problems described below since March of 2014, but did no= t have much of an option other than to wait for gradual improvements. Consi= dering that 11 is nearing official RELEASE, I would think these problems wo= uld be worth consideration. I'm posting in current rather than xorg, becaus= e if there were many others with these problems, it would have been brought= up a long time ago. PROBLEMS: 1. PDF viewers fail to display pdf/ps files correctly. Many files get displ= ayed as blank pages, and I can only get the pdf to display after closing/re= -opening the file several times, or by repeatedly scrolling up/down past th= e seemingly blank page. Pages with an image have more problems than pages w= ith text-only. 2. With the exception of Opera (which is out-dated), all remaining Browsers= fail to display most web pages in a sane manner (Firefox, Seamonkey, Epiph= any, Midori). Chrome is the worst because even with just a blank page it fl= ickers, goes completely white, comes back as a partial image and sometimes = locks X for 1/2 second or so. Problems with the other browsers usually have something to do with sites us= ing php (rather than static content) and I have many problems with images b= eing correctly displayed. Among the symptoms: * Page phases out. Mouse-over or scroll up/down resets the display (midori-= on-linuxquestions.png: https://drive.google.com/file/d/0Bxs_eepbMt6qNTdaQm1= pTFZTMWM/view?usp=3Dsharing) * PHP sites either loose track of last scroll point and jump appx one page = up (example Facebook goes up 4-5 posts to what I just read and repeats acti= on as I try to scroll down), OR they are only partially displayed and need = to be either refreshed (F5) or up/down scrolling to get some kind of displa= y (epiphany-on-forums.freebsd.png: https://drive.google.com/file/d/0Bxs_eep= bMt6qbFJWMW1RZzJsYVU/view?usp=3Dsharing) * I get the same problem when trying to view an image, or a site with many = images. The tab with the image displays one of: a black screen, a single co= lor with vertical interference lines, or a mixture (seamonkey-google-image-= search.png: https://drive.google.com/file/d/0Bxs_eepbMt6qUUJvem11U3c3MVk/vi= ew?usp=3Dsharing) * As a result of all the above, logging in to sites, doing any transactions= which require clicking buttons and check-boxes or filling text fields beco= mes extremely difficult. 3. In Gnome3, menu text is garbled (gnome3-text.png: https://drive.google.c= om/file/d/0Bxs_eepbMt6qWklaSUZLd0luUFk/view?usp=3Dsharing) 4. Chromium causes other programs to mis-behave and display gets corrupted = in the old Win-XP style (chrome-corruption.png: https://drive.google.com/fi= le/d/0Bxs_eepbMt6qMktnOWo3bV93SGM/view?usp=3Dsharing) 5. An update about a month ago is causing problems with /dev/ums0 on Deskto= p (not vt). When I move the mouse it sometimes gets stuck on a menu item of= a program or an item on the Browser (for example a result in google search= ). I have to move the mouse and repeat the previous action in order to get = it unstuck. Sticky lasts about 1/5 of a second. 6. Last week I was getting jpeg file corruption when doing simple processin= g (crop, rotate) in graphics/gthumb. Resulting file would have vertical int= erference lines. After updating the ports/packages yesterday I don't get th= at now. Probably unrelated, but worth mentioning. MY_SYSTEM: + Desktop is usually Fluxbox.
