If you take a screenshot (please try both a screenshot of the window and
a full-screen screenshot), does the display corruption appear in the
screenshot, or does the screenshot show what it *should* have looked
like?

If you run gnome-terminal or another program using vte from a different
terminal such as xterm, are warnings shown?

Are any warnings logged in the systemd journal when you run a program
that uses vte for the first time in a session?

What desktop environment are you using? If it's GNOME, are you in Wayland
or Xorg mode?

What graphics hardware are you using? If both open-source and proprietary
drivers are available, which one are you using? (Some common graphics
hardware on PC: Intel integrated graphics with DRI/Mesa open-source
drivers, AMD Radeon series with DRI/Mesa open-source drivers, NVIDIA
with DRI/Mesa "nouveau" open-source drivers, or NVIDIA with proprietary
"nvidia-driver".)

Do you see similar graphical corruption anywhere else?

gnome-terminal is working fine for me in GNOME 3.36 in a qemu virtual
machine with QXL graphics, and in GNOME 3.38 from experimental on real
hardware (a Lenovo Thinkpad) with Intel graphics, so I'm not going to
be able to debug this unless we can isolate what is happening differently
on your system.
