Thanks for filing the issue.

This issue seems to be similar to the issue :  897906 , hence marking it as duplicate and tentatively CC'ing eirage@. Please feel free to undupe if it is not the case.

Thanks for your quick response and info!

In chrome 70, after changing the Touch Events API via chrome://flags/#touch-events from Disabled to Automatic, free drawing with a touch monitor works fine.

I think this issue is better to be fixed in the fabric.js library, so i will report this issue to https://github.com/fabricjs/fabric.js/issues.

Thanks again.
