Панель Избранного Ubuntu продолжает Исчезать

Панель избранного на правой стороне моего рабочего стола Ubuntu 19.10 продолжает исчезать. Иногда это будут дни, иногда несколько раз в день. Я нашел ссылки здесь: Панель задач продолжает исчезать! и здесь: Ubuntu 16.04 3 января 2018 обновляет порождение проблем экрана/доступа для предыдущих версий.

У меня была эта проблема на предыдущих версиях также, но она поправилась, и теперь она возвратилась в последнем и самом большом.:(

Jan 18 20:15:57 westeros gnome-shell[28046]: Some code accessed the property 'discreteGpuAvailable' on the module 'appDisplay'. That property was defined with 'let' or 'const' inside the module. This was previously supported, but is not correct according to the ES6 standard. Any symbols to be exported from a module must be defined with 'var'. The property access will work as previously for the time being, but please fix your code anyway.
