Создал изображение и поместил в файл "/home/user/.FreeCAD/Gui/images/splash_image.png". С разрешением, видимо, не угадал - при запуске FreeCAD выдаёт в терминал много повторяющихся ошибок:
xcb_shm_create_segment() failed for size 4294443012
QPainter::begin: Paint device returned engine == 0, type: 3
QPainter::setCompositionMode: Painter not active
QWidget::paintEngine: Should no longer be called
QPainter::begin: Paint device returned engine == 0, type: 1
QPainter::setRenderHint: Painter must be active to set rendering hints
QPainter::setPen: Painter not active
QXcbConnection: XCB error: 4 (BadPixmap), sequence: 1021, resource id: 58720646, major code: 54 (FreePixmap), minor code: 0

Но зато он [FreeCAD] запустился.

Запустился только один раз. Скачивание родной заставки и раскладывание её по разным местам не помогает. Судя по strace FreeCAD видит изображение, но всё равно возникает ошибка.

Обновите систему целиком: apt-get update; apt-get dist-upgrade
Если не помогает, то переместите куда-нибудь ~/.config/FreeCAD/FreeCAD.conf
Укажите дистрибутив, используемый видеодрайвер (inxi -G).

Сеанс отладки
Comment 7 smalcom 2022-07-04 01:31:06 MSK 
Обновление системы и удаление каталога "~/.FreeCAD" в целом не помогало. FreeCAD мог 9 раз "упасть", а на 10 запуститься. В ходе отладки (см. файл "Сеанс отладки") обнаружилось, что "device" не существует, а следовательно "чего-то там HighDPI" равно истине. Это насторожило, т. к. ноутбук используется только с VGA-монитором формата 3:4. Удалось обнаружить, что FreeCAD стабильно запускается такой командой:
> QT_AUTO_SCREEN_SCALE_FACTOR=0 freecad

Если предварительно выставить разрешение dpi ниже 96 - "xrandr --dpi 80" или "xrandr --dpi 72", то FreeCAD запускается и без всяких дополнительных переменных:
> freecad

По указанным шагам ошибка не воспроизвелась.
