Tux Paint 0.9.34 — October 2024

All Versions (global issues)

Tux Paint loads very slowly

The first time Tux Paint is launched (for a particular user), it may take a minute or more to respond. The font system used by Tux Paint (Pango) is creating a 'cache' of information about the fonts on your system. Subsequent launches of Tux Paint should be fast.

While the font cache is generated behind the scenes, Tux Paint should remain interactive (showing an animated 'please wait' animation) while this process runs.

Windows-specific issues

Tux Paint doesn't run on Windows 7

As of Tux Paint 0.9.34, Windows 7 is no longer supported by Tux Paint. You can download 0.9.33 from our Tux Paint for Windows 7 download page.

macOS- and OS X-specific issues

'Unidentified developer' error

Recent versions of macOS have default security settings that prevent programs which were downloaded outside of Apple's "App Store" from being launched.

Apple provides instructions here for installing and launching apps from "unidentified developers."

Linux-specific issues

No known issues

Android-specific issues

On Chromebooks, Tux Paint appears very small within a larger window

Look for a pull-down menu at the top of the window. If it shows "Phone", click it and change the setting to "Tablet". If no such option exists, check Tux Paint's "App Info" and make sure the "Preset window sizes" option is enabled.

Some new Magic tools are missing

2025-05-04 — We are investigating the issue.

Apple iOS (iPhone / iPad) specific issues

Tux Paint is an open source project, maintained by a small team of volunteer developers in their spare time. The iOS port was created and published to the App Store by a third party developer. The current version is based on Tux Paint 0.9.31, from July 20, 2023.

Tux Paint was available for iOS, but is no longer in the App Store

Tux Paint was unavailable from the App Store between August 2023 and November 2025, when a new version was made available. However, we've heard that it is not available in all territories, and have asked the developer for details.
