Frequently Asked Questions
No pressure sensitivity
First, check the preferences dialog. Try checking or unchecking the "Use Windows Ink" option. When Windows Ink support is not available, you must have Wintab drivers installed.
Tablet stylus drags canvas
After the Windows 10 Fall Creators Update, Windows also generates a touch event for a tablet stylus motion event.
There are two solutions. The best is to use Windows Ink mode (with "bug workarounds" option unchecked.) If Ink is not available, you will have to uncheck the "scroll with finger" option.
The window is too big and the chat bar goes below the screen
This happens when there are too many docks open and it forces the minimum window height to be larger than the screen height. You can close some docks, tab them together or move them to the other side of the window to release some space.
"Connection timed out" when connecting
A "connection timed out" error (when you know the server should be up) is typically caused by firewalls.
Another common cause is trying to connect to a 1.x server using a 2.x client.
First, check that the hosting user is not behind a NAT. Drawpile can use UPnP, which is supported by most home routers, to automatically set up port forwarding. If the port forwarding works, the private IP address displayed in the status bar (typically starts with 10. or 192.) gets replaced by the public address a few seconds after the session is started.
If the address does not change, you must set up port forwarding manually. See the hosting page for more info.
Note. If the public address starts with "100.64.", it means your ISP doesn't have enough addresses to go around and you're behind carrier-grade NAT. In this case, you must use a remote server to host. (Or use an IPv6 address, if available.)
If you're sure NAT is not the problem, check if the operating system's firewall is not blocking Drawpile's port (27750 by default.) This includes the standard firewall as well as any 3rd party firewalls.
Cannot export video: ffmpeg executable not found
This message is shown in the video export dialog if Ffmpeg is not found. Ffmpeg can be downloaded at ffmpeg.org. Set the path to the ffmpeg executable in Drawpile's preferences dialog.
Can I use Drawpile on my Android tablet or iPad?
An Android port should be technically possible and may be created in the future. (The limiting factor being developer time.)
An iOS version is unfeasible, however, as the App Store terms of service are not compatible with the license used by Drawpile and many of the libraries it depends on.
