A lot of bugs have been fixed, also several performance improvements can be found in the newer NW.js versions. There's no need to stick with the old 10.5 version any more. Try updating your NW.js, it will probably fix your problem. https://www.scirra.com/nwjs
I measure significant performance difference between 10.5 and the new version.
Btw. i've found a workaround for my toolbar problem: Exported project as Html5, and packed with Nodebob. <img src="{SMILIES_PATH}/icon_e_wink.gif" alt=";)" title="Wink">
