I have the same problem with rxvt. I did not know about reverting to courier as a workaround -- thanks!
Emacs-NT also has this problem (but only occasionally). They claim that it is because Windows with cleartype lies about how to compute a bounding box for a font but MS will not share the information. File under "yet another example of why the DOJ consent degree sucks." Jason Rumney from the emacs devel seems to have some good information on the problem. See, for example, http://mail.gnu.org/pipermail/help-emacs-windows/2002-April/001355.html Jason Rumney [EMAIL PROTECTED] writes: No, it doesn't. Sometimes it draws outside the bounding-box for the glyph, which results in a garbaged display when scrolling. That is why sub-pixel anti-aliasing was disabled for 21.2. If you can find any documentation from Microsoft about how to determine the REAL bounding box for a glyph AFTER sub-pixel anti-aliasing is applied, then please tell me. or http://groups.google.com/groups?hl=en&safe=images&selm=m3zo2ugsve.fsf%40nyaumo.btinternet.com Jason Rumney ([EMAIL PROTECTED]) writes: Thanks for the report. Since Microsoft do not seem to be making public what changes they had to make to their own products to fix this (early betas of Windows XP had reports of the same sorts of display problem with all applications, so I assume they have "fixed" it by changing an MFC library or something), there is not a lot we can do. flip Rui Carmo wrote: > Hello there, > > I've been searching the mailing-list archives for posts concerning the vertical >cursor "trails" bug that rxvt exhibits under Windows XP with ClearType, but have >found nothing. > > Steps to reproduce the bug: > - Under Windows XP, activate ClearType (Display Properties|Appearance|Effects|Use >the following method...
