Windows 7 Mouse pointer wrong after zoom

[Eddie Stassen]

This happens in both eeschema and pcbnew when "Do not center and warp cursor on zoom" is unchecked:

1. Position cursor somewhere off center and zoom (scroll wheel or hotkey).
2. The cursor should now be centred.
3. Move the mouse - the cursor immediately jumps back to the position prior to the zoom.

I have seen this is various builds over the last few months, but only under Windows 7

I don't see this issue on my MSYS2 builds, in particular testing version 5730. I don't think any zooming changes has been made between those versions, but did you build KiCad yourself or?

Maybe you can make a video showing the issue.

[Nick Østergaard (nickoe)]

I tested on windows 8.0.

[Eddie Stassen (estassen)]

Just did a fresh build using kicad-winbuilder-3.4 , and I still see the problem. I have tried your binaries from http://www2.futureware.at/~nickoe/, and I don't see the problem, so its possibly related to the kicad-winbuilder environment.

This is not necessary a the kicad-winbuilder environment problem, but a difference between 32bits and 64 bits versions..
AFAIK kicad-winbuilder builds a 32 bits version.

Can you test the 32 bits builds from http://www2.futureware.at/~nickoe/ ?

[Eddie Stassen (estassen)]

Confirmed, I see the problem on your latest 32 bit build as well (bzr5748).

[Eddie Stassen (estassen)]

I downloaded your 64 bit build (bzr5747) and I now see it there as well, so its not a 32/64 bit issue. I'll redo the tests on my home desktop later.

[jean-pierre charras (jp-charras)]

This is not *my* build.

However I am not able to reproduce this issue (Windows 7, 32 bits) both with my build and with kicad-winbuilder.

[Nick Østergaard (nickoe)]

So to summarize, you see the problem on your own build made with KiCad winbuilder and not on my MSYS2 builds?

Are you sure that you are running the correct executable while testing?

If not, please retest starting the exe from the file explorer directly. Otherwise, try to make a video of the issue, such that we can be sure that we don't see the same behavior.

[Eddie Stassen (estassen)]

Ok. this is somewhat embarrassing. I just discovered that the problem is not with Kicad, but with Synergy, which I am running between my Linux and Windows machines. Switch off Synergy, and the problem goes away.

My sincere apologies for wasting everyone's time

Ops this is very old bug. But this happen on:
  F1/F2 key are work fine.
  Using Mouse Scrolling without move the mouse for zoom in/out couple time, the center shifted slowly to other place. I think it should zoom and stay around the original center wherever the mouse original at.

Hello, it anyone got my bug report? Or should I create a new one apart from this ?

[Seth Hillbrand (sethh)]

You should definitely make a new report. The data in this report do not correspond with your issue as the original reporter made a mistake.

In your revised report, please state what you observe with Center and warp on as well as Center and Warp off. Also, please note which canvas and application you are using.
