So am still getting scroll issues (rc-12)

  1. When going to a bookmark, zoom to the origin or full model zoom. The first click of one of the three scroll buttons causes a sticky effect (like the button is still depressed like I'm holding the mouse clicker down) for about 5 seconds.
  2. I am also getting the same first-click scroll issue where the screen pans to a different area of the canvas, though not as bad as early beta versions. This will not always happen, but when it does happen when going to a bookmark, zooming to the origin, or full model zoom.
  3. It appears the larger the model gets the less the "shift and drag" panning works to the point that in Matt's port model I'm doing it does not work at all.

    1. Sticky scroll buttons. Reproduced - it seems to happen everywhere. Not sure there's much I can do about it, it seems to be Electron behaviour.
    2. First click scroll issue - I can reproduce this after goto bookmark, but reset zoom and zoom to fit work correctly AFACT. The bookmark one is on me - I forgot about bookmarks when I was implementing the mitigation of this problem, so that's an easy fix.
    3. Yes - I would expect panning and scrollbars gets less useful as the model gets bigger. What is effective is scroll wheel zooming - zoom out, then zoom into the area of interest.

    Renaming this to "sticky scroll issue", referring to point no. 1 above, and backlogging it. I have committed a fix for point no. 2 (at least the bookmark not resetting scoll, as the other scenarios don't reproduce).

    I believe I noticed the scroll issue (issue #2) happens as well with you use the "find definition" in the context menu.

    We've upgraded Electron since this issue was raise, and I don't see the sticky buttons any more.
