Linux Vapoursynth problems

[Selur]

Some UI elements (typically the bold headers on almost all tabs) look displaced on a 4k screen. Is this known/relevant/important enough

Have you tried using another theme?

renice: failed to set priority for 9057 (process ID): Permission denied

This happens in case the Hybrid used is not allowed to adjust the priority of the current thread.
I doubt it is related to the problem, but I'll compile a dev linux version for you to test, just to be sure.
no clue what's causing the:

malloc_consolidate(): invalid chunk size
Aborted (core dumped)

Thanks for the new version. Unfortunately the problem remains.

As for the UI:
It looks like it's dependent on the DE used, not the theme. The UI looks good in KDE, but then KDE uses quite a special scaling mechanism.
I know 4k is a difficult topic, especially in Linux with its many DEs...

Best regards,

Some distros also use modified Qt libraries which also sometimes causes strange problems. :/

Side note:
Since you wrote that you use Linux Mint, I'm surprised that you use KDE, since iirc Mint dropped the KDE support last year,... so it might be a problem with the combination of Mint&KDE,..

I use Mint/Cinnamon as my main system, but I have a test VM with Manjaro/KDE...

I'll setup a Mint VM tomorrow and try to reproduce the issue.

Good news.
I managed to reproduce the issue.
What I did:

• Installed 64bit Mint Cinanammon 19.1 in a VM
  
• Added the repository of djpj: (used this since Mint 19.1 is based on Ubuntu 18.04)
  • sudo add-apt-repository ppa:djcj/hybrid
    
• Updated the system
  • sudo apt-get update && sudo apt-get -y dist-upgrade && sudo apt-get -y autoremove && sudo apt-get -y autoclean && sudo reboot
    Problem here was that this aported. Then trying
    

    sudo apt-get --fix-broken install

    it would will simply loop
    

    dpkg: dependency problems prevent processing triggers for gconf2:
    gconf2 depends on default-dbus-session-bus | dbus-session-bus; however:
    Package default-dbus-session-bus is not installed.
    Package dbus-user-session which provides default-dbus-session-bus is not configured yet.
    Package dbus-session-bus is not installed.
    Package dbus-user-session which provides dbus-session-bus is not configured yet.
    Package dbus-x11 which provides dbus-session-bus is not configured yet.
    dpkg: error processing package gconf2 (--configure):
    dependency problems - leaving triggers unprocessed

  • Then I called 'sudo dpkg --configure -a' and after that 'sudo apt-get --fix-broken install'. Now calling my update call from above worked.
    
• Install Hybrid, it's tools and Vapoursynth
  • sudo apt-get install hybrid hybrid-tools hybrid-vapoursynth-extension
    
• Calling 'hybrid' in a terminal, started the hybrid installation, restarting hybrid two times seems that Hybrid found all the tools.
  
• Opening Hybrid
  • Start Hybrid
    
  • Loading the source sample I uploaded to the vm.
    
  • Starting the Vapoursynth Preview (-> preview opened)
    
  • Closing the preview (-> Hybrid crashed)
    

-> Now looking to how to debug this.

-> Using the dev version (downloaded it, made it executable and used it), I could not reproduce the issue.
