 At least on the one amd64 host I've tried so far, the wrong glyph is
 used for the text cursor in the username/password fields.  It appears
 to be using the "set edit point" cursor normally used for the mouse
 pointer rather than the typical plain vertical line.

 And as martin@ noted, it seems shifted down a bit so it glitches the
 pixels along the bottom edge of the entry field.

 With -8 amd64 and pkgsrc X11, I just get black fields in the xdm requester
 for both username and password. Started... maybe 6 weeks ago?

 Cheerio,

 You need to update the resources for it.

 Looking a bit more carefully at the 'xdm' login widget in netbsd-8, the
 cursor does appear to be the "set edit point" cursor, or look quite
 similar to it.  It's just properly centered in the edit field.

 So the 'xdm' in -current has it shifted down so it steps on the pixels
 in the lower edge of the box, as noted for font data in the initial
 submission of this PR.

 What specifically? My xdm's resources are heavily customized, but 
 nothing in the differences really stands out.

 Cheerio,

 Check for new inpColor: entries.

 I see the problem description on a system with:

 $ grep -r inpColor /etc/X11
 /etc/X11/xdm/Xresources:xlogin*inpColor: grey80

 which appears to match

 There are two issues. The edit field themselves are broken, and the background
 colour is black by default if the resources are not up to date.

 With the fixed resources you should see the edit fields and the content
 you edit (but still display is corrupted and texts are a few pixel down).

 Possibly interesting data point:  The systems where I see the shifted
 cursor/font corruption all use a DRM/KMS video driver (radeon, intel).

 I recently booted a system that uses the intel driver but is not supported
 by DRM/KMS nor UMS (i82810e-based).

 On this system, the 'xdm' login widget edit fields have the cursor and
 fonts properly centered and does not experience corruption/glitching
 when typing the username or backspacing.

 For the trifecta I'll see about trying a known-working nouveau-equipped
 machine as well as other machines which use non-DRM/KMS video (old
 radeon, rage128, via, SiS, etc.).

 hmmm, i wonder if we can make rc.d/xdm fail to startup if
 that is missing?

 the postinstall could be smarter too.. anyone? :)

 The nouveau-equipped machine shows the same shifted cursor/font with
 glitched borders and leftover character bits.

 For completeness, on a machine using the intel DRM/KMS driver with a
 real i82915 device, the downward shift seems less pronounced than on
 the other systems, but it's still there and still glitches, although
 less so.

 A system with a VIA chipset and using "viadrmums* at drm?" also shows
 the corruption/glitching.  Additionally, upon aborting 'xdm' with <ctrl-R>
 (takes 4 presses) and returning to the regular VGA text console, the
 contrast is reduced.  The background seems a little brighter and
 the text noticably dimmer.

 A system with an XGI Volari Z7, with "sisdrm* at drm?" in the kernel
 ("sis" xorg driver) likewise displays the corruption/glitching.  Rebooting
 with GENERIC (i.e., w/o the "sisdrm" driver) made no difference.
