drawing the stroke for a gesture creates black tiles on screen

[Peter Troesch]

Running 17.10

When drawing a stroke for a gesture, a trail of black tiles follows the stroke before being filled with the original window background.

this bug is fixed with https://github.com/thjaeger/easystroke/commit/d14b2740bf3b0ec867d7a0abe4e1f64fb6687aba which is in git master

It seems like easystroke on ubuntu is still built from 0.6.0 release and not from master.

As master is also outdated, you will need to add at least these patches (ubuntu package has also two of these patches):
 - [fix build failed in libsignc++ version 2.5.1 or newer](https://github.com/thjaeger/easystroke/pull/9/commits/22b28d25bb696e37e73b4bc641439b3db9f564ed) build fix
 - [Remove abs(float) function that clashes with std::abs(float)](https://github.com/thjaeger/easystroke/pull/8/commits/9e2c32390c5c253aade3bb703e51841748d2c37e) build fix
 - [fixed recurring crash when trying to render 0x0 tray icon](https://github.com/thjaeger/easystroke/pull/10/commits/140b9cae66ba874bf0994eea71210baf417a136e) bug fix
 - [dont-ignore-xshape-when-saving.patch](https://aur.archlinux.org/cgit/aur.git/tree/dont-ignore-xshape-when-saving.patch?h=easystroke-git) bug fix, fixes [Changing 'method to show gestures' to Xshape does not persist](https://bugs.launchpad.net/ubuntu/+source/easystroke/+bug/1728746)
- [switch from fork to g_spawn_async](https://github.com/thjaeger/easystroke/pull/6/commits/0e60f1630fc6267fcaf287afef3f8c5eaafd3dd9) bug fix `This fixes a serious bug that can lead to system instability. Without this patch, if a 'Command' action is commonly used, it will lead to so many zombie processes that the OS will be unable to launch additional processes.`

for the non-tech savvy, here is an already built package:
http://openartisthq.org/easystroke/easystroke_0.6.0-0ubuntu8_amd64.deb

for people who do not want to install packages from outside the debian packages mechanism, I also provide the already patched sources with the used patches:
http://openartisthq.org/easystroke/patched-easystroke-master.tar.bz2

Let me know if this helps ;-)

Can we hope for a new maintainer of this awesome project ?
