Ubuntu 20.04

PrusaSlicer takes half a minute to start up

Symptom

PrusaSlicer takes half a minute to start up when you use GTK2 build (the build which doesn't contain the string GTK3 in the filename).

1. Solution (workaround)

You can use the GTK3 build of PrusaSlicer if it is available. We start producing these builds since PrusaSlicer 2.3.0-alpha1. GTK3 build you can recognize by the string GTK3 in the filename.

2. Solution (workaround)

If for some reasons you don't want to use GTK3 build instead of GTK2 build, then based on the following discussion https://itsfoss.community/t/solved-apps-opening-too-slow-in-ubuntu-20-04/4578, you need to do the following steps:

  1. Install package appmenu-gtk2-module. Use sudo apt-get install appmenu-gtk2-module
  2. Reboots your computer.
