Expected behavior

3D globe should work.

Actual behavior

Get error message from CesiumWidget.

Steps to reproduce the problem

Just run Cate Desktop, zoom in/out.

Workaround

Click VIEW panel, switch from 3D Globe to 2D Map.

Specifications

Mac OS X Yosemite, 10.10.5
Cate 0.9.0-dev.2

From https://bugs.chromium.org/p/chromium/issues/detail?id=656989 it seems that configuring Chromium to use --disable_chromium_framebuffer_multisample fixes the issue for time being.

Problem still occurs regularly:

Seems to originate from WebGL out of memory and/or lost WebGL context:

Next time it looked like:

[forman]

First thing we do in Electron's main process is now:

if (process.platform === 'darwin') {
    // Try getting around https://github.com/CCI-Tools/cate-desktop/issues/32
    // See https://electron.atom.io/docs/api/app/#appcommandlineappendswitchswitch-value
    // See https://bugs.chromium.org/p/chromium/issues/detail?id=682075&desc=2
    app.commandLine.appendSwitch('disable_chromium_framebuffer_multisample');
    app.commandLine.appendSwitch('disable_depth_texture');
}

And the problem seems to disappear, at least on OS X 10.10.5
