Так ведь пишет именно то, что старый формат. Исправьте в соответствии с новым, тогда и глюки пропадут.

vasek, спасибо за ответ и линк, но в данном случае это не работает:
и решил проверить сам — переименовал mpv.png в директориях 16х16, 32х32, 64х64 — в итоге фиолетовая иконка исчезла (осталась только одна в самой программе — ее менять не стал, не мешает). Значит если вместо этой png поместить другую, то будет новая иконка........ Вывод — что то делал неправильно.
Давайте ещё раз по тексту.
Первым делом я меняю дефолтные фиолетовые иконки, находящиеся в исходниках (etc/) на нужные мне:

После чего собственно и компилирую:

После чего появляются оные в директории /usr/local/share/icons/hicolor/{16x16,32x32,64x64}



А так же, иконка самого приложения:

Девелопер пока молчит.
Возможно, какой кэш где сидит? o_O
Не решит. Скрипт тащит иконки именно из той директории, куда я закидываю свои и как я уже говорил, потом они появляются в /usr/local/share/icons/hicolor, только это ничего не меняет, лого в трее всё то же.
Ладно, попробую связаться с девелопером. Тут либо всё проще, либо очень мудрЁно.
Очень намудрил. Не удивлюсь, что компилятор её подтягивает из сети. Надо будет завтра ещё раз перелопатить весь выхлоп.
Я пробовал и AUR mpv-git, и исходники с гитхаба.
PS
Кстати, именно этой иконки нет в исходниках (я не нашёл по крайней мере).
Так я так и делал. Подменил иконки на нужные и начал компиляцию. Смех в том, что в конце компилятор показывает новые пути установленных иконок из etc в исходниках как /usr/local/share/icons/hicolor/.... И при просмотре это именно те самые, что я подменил вначале. Т.е., по логике, должна появляться новая, а выскакивает всё равно эта фиолетовая зараза. Откуда он её тянет теперь - вообще непонятно. Да, пожалуй постучусь к нему. Спасибо.
vasek, спасибо за ответ и линк, но в данном случае это не работает:
cat /usr/share/applications/mpv.desktop | grep 'Icon'
Icon=/usr/share/icons/nouveGnomeGray/48x48/apps/mpv.png
На всякий случай ребутнулся. Всё по-прежнему.
Спасибо, понял. Почти.
ДрУги! Как сменить дефолтную иконку на тематическую? Уже и поудолял всё связанное с mpv из hicolor и gnome. Кеш обновил. А она всёравно выскакивает.
На гитхабе прочитал, что она зашита в бинарник и нужно перекомпилировать.
параметры запуска?

скорее всего команда запуска...
Ха!!
Как оказалось, я - кривда!
Всё парни, отбой поход!

indeviral, Haron_Prime, спасибо за хороший пинок в правильную сторону.
Я себя таким тормозом не ощущал лет-так пять...
Видать, моё о себе великомнение не позволило даже допустить ошибки в меню запуска приложений, чтобы заглянуть туда. :)))
