That was the solution. I checked the resolution before the upgrade with
xdpyinfo | grep resolution (Tip from the German list): 75 dpi.
Afterwards: 96 dpi. Setting it to 75 solved the issue.
I'd still like to know what exactly changed and if 75 or 96 is the
correct value. Nevertheless, I have Xorg server 1.6 running and it
looks fine.
Divide your screen resolution (pixels) by its visible area (inches) to
get DPI. For example my monitor screen is 16 inches wide and 12 inches
tall and I use 1600x1200 resolution. That is 100dpi. In my system this
is autodetected when xorg starts (maybe the nvidia drivers do it?).
This is a VMware virtual machine using a virtual monitor on a physical
machine with two physical monitors. I'm not sure whether calculating DPI
that way would lead to meaningfull results for the virtual machine. This
whole hard setting of DPI for a monitor seems anachronistic to me.
I think the DPI of the monitor would still be valid in the vmware
window, just set it to that of your physical monitor and I think it
should be the same. The size of 1 pixel in the vmware window should be
the same as the size of 1 pixel in your monitor normally. If your two
monitors are not the same DPI then things could be complicated though.
I don't use multi-monitors so I'm unfamiliar with how that would work.
In my Xorg.0.log I see these lines among others from the Nvidia driver
initialization:
(II) NVIDIA(0): Virtual screen size determined to be 2048 x 1152
(--) NVIDIA(0): DPI set to (101, 100); computed from UseEdidDpi X config
(--) NVIDIA(0): option
Not sure how it works for other video drivers. On this one, at least,
the DPI is set automatically.
