Subject: bug#22715: 25.0.91; Point randomly jumps during key entry
Date: Tue, 16 Feb 2016 20:39:49 -0500 [thread overview]
Message-ID: <20160217013949.GE2649@srevilak.net> (raw)

First, please accept my apologies for the poor bug report. I'm calling
it a poor bug report because I've been unable to find a simple recipe
that easily reproduces the behavior I'm seeing.
The behavior itself is easy to describe: while providing keyboard input,
sometimes point jumps to a (seemingly) random place in the buffer.
Some examples
- while holding the UP arrow to slowly scroll upwards in the current
buffer, point suddenly `jumps' up, over several screenfuls of text
- while typing (ordinary alphanumeric text), point jumps to a line
near the top of the file. I've noticed this most often when using
emacs to write java code. I'll be typing away in the body of a
method, and point will jump to a position in the file header
comment, several hundred lines earlier.
This doesn't happen very often. Perhaps 3--4 times during a work day.
I have not found a way to make it happen on demand.
I've experienced this behavior in 25.0.90 and 25.0.91, but not in
earlier versions.
I typically see this behavior in java-mode and org-mode. That said, the
vast majority of my emacs usage involves java-mode and org-mode.
I've seen this behavior on two different x86_64 GNU/Linux systems.
One system runs Redhat 6.4, and the other runs OpenSUSE 13.2. Both
systems have `standard' USB keyboards, and optical mice.
If I'm able to find a nice set of steps to reproduce, I'll add them to
this bug report.
If there are suggestions for gathering/providing more information,
please let me know, and I'll gladly try them.
