Bug ID: 119233
Summary: Trackpad click handling very slow on MacOS, leads to
randomly moving objects in Draw
Product: LibreOffice
Version: 5.2.6.2 release
Hardware: x86 (IA32)
OS: Mac OS X (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Draw
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: ken.shirr...@gmail.com
Description:
When I click on an object to select it and then move the cursor after
releasing, Draw often acts as if I was still holding the object, moving it
unexpectedly. I need to wait a while after selecting an object before I can
move the cursor to give LibreOffice time to deal with the click.
Steps to Reproduce:
1. Using the trackpad, click and release on an object to select it
2. Move cursor using trackpad, immediately after the previous step
Actual Results:
The object is selected and dragged. I then need to move the object back to
where it was, which is annoying.
This is also laggy, happening about 1/3 second after I move the cursor.
Expected Results:
The object is selected, then the cursor moves without moving the object. This
is the behavior I get if I do things slooowly.
Reproducible: Sometimes
User Profile Reset: Yes
Additional Info:
If I wait a long time (> .5 second) between the release and the cursor move, it
works correctly. But with normal trackpad usage I usually get the bad behavior.
I have a clear gap between the release and the move when I see the problem; I'm
definitely not starting the move before I unclick. I want to emphasize that I'm
not doing crazy speed demon moves with the trackpad, just using it at a normal
pace as with any other program.
It seems like LibreOffice is slow in processing mouse events. I suspect that it
is processing the drag event before the unclick event even though the drag
happens afterwards.
This happens with OpenGL disabled or enabled.
