Gitching dialog

/me too, but also all ncurses-drawing apps are glitching out: every
updated/redrawn line is becoming misaligned, especially visible on solid
backgrounds.

It all stared after kde-gear update to the 22.12 version.

Attached an example with simple one-liner showing this glitching in `dialog` 
program (other ncurses apps show the same behaviour).

```
for i in `seq 0 10 100`; do echo ${i} | dialog --gauge "Glitching progress..."
10 60 ; sleep 0.5; done
```

I also have scaling enabled:
```
kk at kk ~ $ printenv | grep SCALE
QT_SCREEN_SCALE_FACTORS=DP-0=1.25;DP-1=1.25;HDMI-0=1.25;DP-2=1.25;
QT_AUTO_SCREEN_SCALE_FACTOR=0
kk at kk ~ $ 
```

After disabling the scaling, the glitching stops.

This new, fancy word-mode is disabled. 
X11, proprietary nvidia drivers.
