Slow startup Ubuntu 19.10

[WZ9V]

Version: 2.1.0+linux64
Build: PrusaSlicer-2.1.0+linux64-201909160925
Operating System: Unix
System Architecture: 64 bit
System Version: Linux 5.3.0-23-generic x86_64

There is a very long pause when starting PrusaSlicer on Ubuntu 19.10. I didn't see this before on Linux Mint which I believe is based on Ubuntu 18

Went back to Ubuntu Desktop 18.04 and the startup was normal again.

I want to share that the exact same happens on 19.1. haven't tried LTS but it works fine on windows.
app functions and works normally and smoothly after it opened

I can confirm the same. Ubuntu 19.10 is very slow to open. 18.04 was fine. I also tried Pop OS 19.10 and it opened slow as well. This is the appimage. I was going to try to compile from source code but I kept running into dependency issues and couldn't solve a few of them so I couldn't see if compiled on my system would be any different than the appimage.

I really wish we had a .deb of a flatpak or something. the appimage doesn't even have an icon

Also seeing the same issue on Pop OS 19.10 with either the Appimage or the extracted archive.

This is happening for Ubuntu 20.04 preview as well with the Appimage.

After having the same issue with Okular (startup times ~30 secs), I found this stackexchange post:

https://askubuntu.com/questions/1184774/some-applications-on-ubuntu-19-10-very-slow-to-start

The gist:

sudo apt-get install appmenu-gtk2-module

After a reboot everything was working blazingly fast again.
I would suggest to add the above package to the dependencies for gtk based systems.

Hi @AmyTheCute,
there will be a flatpak build on flathub in the next hours.

Is this issue still valid? Does it happen with 2.3.0?

I believe this issue is a platform bug, not PrusaSlicer bug.
On those systems you most likely may run PrusaSlicer-2.3.0 built against GTK3 and the issue will go away.

@bubnikv @lukasmatena this can be closed, or?

Closing.
