Bug ID: 377323
Summary: Poor mouse movement implementation
Product: plasma4
Version: unspecified
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: mouse actions
Assignee: plasma-b...@kde.org
Reporter: bobert.campb...@gmail.com
CC: chan...@gmail.com
Target Milestone: ---
It seems to queue up all mouse movement messages and process every message.
For me this can result in 10 second delays when I sweep my mouse across an
application that draws tool tips and the like.
This happens to me on the plasma task manager widget and several apps include
VLC. I can slowly watch all the mouse movement messages get processed. This
is resulting in a horrendous user experience.
This reeks of poor implementation. I'm pretty sure the correct way to handle
mouse movement is to set a flag when the mouse is moved and when you are able
to then process it and get the current mouse location. That way by the time
you are processing the message, if your system has been busy, you are only
processing the latest mouse movement message and that is it, the rest should be
ignored, except for any message preceding a click.
