Hi. I'm limited knowledge. But, as to just pondering some possibilities:
1. Did you recently change the resolution setting of your desktop?
2. Did you change any font(s) or font settings?
3a. If your X server somehow changed the resolution setting on its dot pitch
Code:
al@P5Q:~/.kde/share/apps/konsole/profiles$ xdpyinfo | grep res
resolution: 108x115 dots per inch
(I try to not run above 100 dpi but my old eyes needed things to be just even yet a bit larger on screen).
3b. (in konsole) If you somehow switched from a 75 dpi font to a 100 dpi font or vice versus.
FWIW in konsole on Slackware 12.2 I had created a profile and named it term and then in konsole I chose this profile named term as my default profile.
FWIW here that profile is:
Code:
al@P5Q:~/.kde/share/apps/konsole/profiles$ cat term
