С плохим состоянием видеосистемы под линуксами.

Пробуй чистый профиль для браузера. Если не поможет, то отключи GPU ускорение в настройках.

Набираешь в коммандной строке chromium и наблюдаешь за ошибками:

blitz@inode ~/nsdap/1488 % chromium

Плюсую за чистый профиль. Неоднократно помогала чистка.

Как собираешься исправлять подобное?
В официальный Хром поддержку аппаратного ускорения таки не завезли, но если собирать самому, можно исправить.

Ага.
Но хотелось бы тебе большего, безусловно.

Оценив затраты времени, решается, что не стоит усилий поделие.
