Another thing: This problem actually appears even without FVWM's
ManualPlacement, i.e. if the window is displayed immediately. So
I suppose that it is likely to occur with other window managers.
A simple command to reproduce the issue:
echo 'set terminal wxt; plot x' | gnuplot -persist

The issue seems specific to gnuplot under particular conditions.
See below.
Now, I can reproduce the bug on my other machine. I upgraded some
packages, and I
Can you see if other wxt applications work on a system that's exhibiting
this problem?

- You say "plot x" and you get a plot window, but it's all white, or

Package: gnuplot-qt
Version: 6.0.0+dfsg1-1
Severity: grave
Justification: renders package unusable
