Sample project to reproduce the following Cocoa WebView bug:
When using WebViews hosted within an NSTabView Apple's documentation recommends to use the setHostWindow:YES API of the WebView class. This works around the issue that "Plug-ins and JavaScript depend on a window to function properly even if the web view is not in an actual window".
However, when using this API and switching back and forth between the tabs, the Plugin's contents suddenly flip vertically and horizontally.
For me, this is reproducible with the following systems/configurations:
- OS X 10.10.2 with Safari 8.0.3 (10600.3.18)
- OS X 10.9.5 with Safari 7.1.3 (9537.85.12.18)
- OS X 10.9.5 with Safari 7.1.2 (9537.85.11.5)
I can NOT reproduce it with the following systems/configurations:
- OS X 10.8.5 with Safari 6.2.3 (8537.85.12.18)
Furthermore, it's only reproducible if the application is targeting the 64 bit architecture. For this reason there are two targets included in the sample project, one targeting 32 bit (WebViewPluginTest x86) and one targeting 64 bit (WebViewPluginTest x64).
###Steps to reproduce
- Start the x64 based sample.
- Switch from the 'No Plugin' tab to the 'Quick Time' tab (or 'Flash' if installed and configured properly).
- At this stage everything is working as expected.
- Now switch back to the 'No Plugin' tab and once again back to the 'Quick Time' tab.
- Now the Quick Time logo on the right is flipped vertically and horizontally. (see screenshots below)
