The open-source painting software Krita 4.0.4 was released a few days ago as the fourth bugfix release for Krita 4.0 series.

Here is the list of bug fixes in Krita 4.0.4:

  • Fix artefacts when painting with a pixel brush on a transparency mask

  • Fix a crash when editing a transform mask
  • Add preset memory to the Ten Brushes Script, to make switching back and forward between brush presets more smooth.
  • Improve the performance of the stroke layer style

  • Keep the alpha channel when applying the threshold filter
  • Do not use the name of the bundle file as a tag automatically
  • Fix selecting colors when using the python palette docker script
  • Restore the last used colors on starting Krita, not when creating a new view
  • Allow creating a layer group if the currently selected node is a mask
  • Show the correct opacity in the segment gradient editor
  • Remove the obsolete shortcuts for the old text and artistic text tool
  • Allow setting the multibrush angle in fractions
  • Fix painting of pass-through group layers in isolated mode
  • Improve performance of loading OpenEXR files
  • Autosaving will now happen even if Krita is kept very busy
  • Improve loading of the default language
  • Fix color picking when double-clicking
  • Fix inconsistent frame numbering when calling FFMpeg
  • Fix channel swizzling problem on macOS, where in 16 and 32 bits floating point channel depths red and blue would be swapped
  • Fix accepting touch events with recent Qt versions
  • Fix integration with the Breeze theme: Krita no longer tries to create widgets in threads
  • Fix the batch mode flag when loading images from Python

Download / Install Krita 4.0.4 in Ubuntu:

Krita Lime PPA contains Krita packages for Ubuntu 18.04 and Ubuntu 17.10. The latest 4.0.4 packages will be made into the PPA in a few days.

Krita website offers Appimage, a single executable (non-install) file to launch the software. It’s available for download at the link below:

Krita 4.0.4 Appimage

Once you get the appimage, do:

The latest Mesa 3D graphics library 18.1.1 now can be easily installed in Ubuntu 18.04 LTS via PPA.

For those sticking to the open-source drivers and need graphics performance improvements (e.g. for playing games), Canonical’s Timo Aaltonen has pushed Mesa 18.1.1 in the x-updates PPA.

1. Open terminal either via Ctrl+Alt+T or by searching for ‘Terminal’ from software launcher. When it opens, run command:

sudo add-apt-repository ppa:ubuntu-x-swat/updates

Type your password (no asterisks while typing due to security reason) when it prompts and hit Enter to continue.

2. After adding the PPA, do system update via command:

sudo apt-get dist-upgrade

apt-get update is not required any more in Ubuntu 18.04 since adding PPA automatically refreshes system repositories.

3. Finally check your driver version via command:

glxinfo | grep "OpenGL version"


To restore changes and downgrade to the default drives shipped in Ubuntu 18.04, run command:

sudo apt-get install ppa-purge && sudo ppa-purge ppa:ubuntu-x-swat/updates
