Logs
====
There are no logs that reports or shows any of the anomalies/bug present
into PekWM- extending to dmesg and x11's error logs.
Steps to reproduce
==================
# First scenario
* Open any program (ex. file manager, browser);
* Start scrolling with the trackpad/touchpad (side-scrolling or 2-finger scroll) at a fast speed;
* At a certain point, pekwm will start to freeze out of nowhere;
* The Window Manager should be unable to recognize any input, excluding any mouse movement;
* To temporarily resolve the issue, press any key on the keyboard- afterwards, the X-session should catch up with any input in a delayed way;
# Second scenario
* Open any program;
* Connect to the device a graphics tablet;
* Start using the device regularly with the stylus pointer, with any variable speed;
* PekWM will start freezing, still repeating the same behavior of any mouse event being ignored with the exclusion of mouse movements;
* Again, any key tap should resolve temporarily the issue + delayed input on X11's behalf;
Summary and Assumptions
=======================
The pattern seems to be related to any cursor input that is way too fast
to handle for PekWM, causing hang-ups.
As far as i have started diagnosing the main issue and excluding
probable causes to this behavior (like the compositor or the WM's
configurations):
the following seems to be agnostic to any of these elements.
Expected outcome
================
PekWM should recognize fast cursor input without issues and no hang-ups.
Suggestions & Patches
=====================
According to PekWM's upstream page, this issue has been reported to
upstream twice (see: https://github.com/pekwm/pekwm/issues/4 &
https://github.com/pekwm/pekwm/issues/104) and, despite any attempt to
fix the issue under v.0.1.18, newer releases of the following has
definitely fixed the following bug.
If there's a mantainer for PekWM under Debian, it would
be greatly appreciated if PekWM will get either an upgrade to v0.2.0 or
v0.3.0 (latest release, as of 23th Jaunary 2023) to mitigate the
following bug and starting the process to port it under the stable
branch- this avoiding to build the package from source and cause
probable conflicts with a current Debian install.
Thanks for the attention taken to this bug report,
