 When you start panning, very slowly, by a little bit, there is a period
 when it looks like the view window tries to center itself, so it jumps
 back and forth between where it used to be and where the mouse is going,
 until it's far enough and it snaps out of it and at the same time the
 scroll bars appear.

Re: [Kicad-developers] Jumpy canvas on other platforms?

[Wayne Stambaugh]

I'm still seeing this issue on windows as of commit 218f66a08.  The
scrollbars are shown greyed out initially after the zoom extents but it
appears that on windows, the paint area does not include the scollbar
width when the scollbar is greyed out but does include them as soon as
you pan and they get enabled.  This is what is causing the jumpy
behavior.  The drawing canvas size is be reported differently even
though the scrollbars are always shown.

Thanks, everyone.  I think it’s more sensitive to a trackpad than mouse, but I 
merged a fix yesterday anyway.

Re: [Kicad-developers] Jumpy canvas on other platforms?

I see it now.  I was moving the cursor too fast.  You have to move it
very slowly to see the issue.  Hmm, never noticed that before.

Re: [Kicad-developers] Jumpy canvas on other platforms?

[Andrey Kuznetsov]

I notice the jerkiness on WIndows!

When you start panning, very slowly, by a little bit, there is a period
when it looks like the view window tries to center itself, so it jumps back
and forth between where it used to be and where the mouse is going, until
it's far enough and it snaps out of it and at the same time the scroll bars
appear.

I'm not seeing this on my windows 7 builds.  The panning after zoom
extents works smoothly.  I even tried resizing the main frame several
times but I still didn't notice it.

There is actually code in there to make them always on, but there seems to be 
something defeating it.  I’ll poke around some more.

Re: [Kicad-developers] Jumpy canvas on other platforms?

[Jon Evans]

Ah yes, I can reproduce that on Windows too.  I guess I didn't notice
before because generally the scrollbars are visible (I noticed that "zoom
extents" doesnt *always* result in the scrollbars being hidden, for
whatever reason)
Any reason why we hide the scrollbars?  Seems like it might be simpler to
just always show them...

Do a “fit to window” and then pan left/right… I use the touchpad.
After “fit to window” there is no scrollbar.
When the scrollbar comes back due to panning, I see almost always a small shift 
of the whole view down and then up again.
Sometimes, but not always if you just pan left/right it will make this small 
jump downwards every time you cross center, just as if it would “snap" to 
middle position.

Re: [Kicad-developers] Jumpy canvas on other platforms?

[Jeff Young]

Hi Jon,

Yes, I meant the zoom extents.

When you open the file it auto-zooms to fit.  Therefore you have no scrollbars. 
 But panning with the trackpad (or I imagine middle mouse button) causes it to 
show the scroll bar which “jumps” the schematic by the width and height of the 
scrollbars.  With the trackpad at least sometimes it jumps right back and the 
scroll bars go away again (but that might just be hysteresis in the trackpad 
motion detection).

Cheers,
Jeff.

Maybe I don't really understand what you mean, but I can't see any
jumpiness on Linux when panning around (with middle-mouse drag).
What do you mean by "it automatically fits to window, so there's not really
any place to go"?  It does not do any kind of auto-fitting except for the
zoom-extents on file load on Linux, and I don't have my Mac machine handy
to compare.

[Kicad-developers] Jumpy canvas on other platforms?

[Jeff Young]

If I open an eeschema file on OSX and pan around (it automatically fits to 
window, so there’s not really any place to go), the screen jumps around a bit.  
True also on other platforms, or Mac-specific?

Thanks,
Jeff.
