Aha! For some reason, mozilla's fonts are sized differently than galeon's on my machine, so mozilla doesn't show corruption in the test case I was using for galeon, but I _can_ get it to show corruption on some different text. Sorry about that. I was also insufficiently vigorous about trying to find instances of corruption; by searching diligently, I was able to find corruption even in galeon at 100 DPI, which I had reported as working previously. It's certainly much more subtle at 100 DPI; I'd been running at 100 DPI for quite a while without seeing it (I used to get it all the time, when I scrolled), but with effort I was able to find it again at 100 DPI now. The short version of the story is that all the browsers get corruption in all configurations I tested _except_ when screen_resolution is set to 96. I would therefore recommend reopening the upstream bug, and adding: // Workaround for off-by-one display errors // See http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=148916 pref("browser.display.screen_resolution", 96); ... to Debian's /etc/mozilla/prefs.js until upstream gets a fix together. That's assuming, of course, that someone else can reproduce this, and it's not just monkeys in my /usr/bin or something. A quick sanity check would be to open mozilla (with 100 DPI and screen_resolution set to 0) and drag an xterm over part of the URL bar and back off again: On my system, the obscured part of the URL bar gets shifted vertically by a pixel or so. BTW, adding 'user_pref("browser.display.screen_resolution", 96);' to /etc/mozilla/prefs.js does nothing in any browser AFAICS, but adding 'pref("browser.display.screen_resolution", 96);' to /etc/mozilla/prefs.js fixes it in all browsers for me. > Did you check for corruptions of your display with: > - firefox > - epiphany > - galeon Yes; all of those have corruption at 91x90 and 100x100 DPI (with screen_resolution set to 0), but not when screen_resolution is set to 96. For the record, the full results are below. They're very boring. The corruption test I was using was to drag an xterm chaotically around over the browser text. ---+ mozilla 1.7.8-1 1.

For that test, I left the screen_resolution pref at 0. > I asked for the upstream bug to be reopened, thinking this probably > ain't Galeon specific. It certainly doesn't look like it is. It might be a general (font-) rendering problem on my system, I guess, though I've not seen this sort of corruption in any other application that I can remember. Certainly the corruption in the URL bar of mozilla and the tab labels of firefox argue for it being specific to me; if that were happening everywhere, I'd think someone would have noticed before now. :-) -- Andrew Moise <[EMAIL PROTECTED]>
