It seems now the export works correctly. Version of the blender f606f588455e from 20.05.2019.
Version fbx 4.14.8.

Can you please try again with latest version of Blender2.8 ? Several things have been fixed recently in depsgraph/evaluation of meshes, that affect all IO addons (among other things), so that issue might have been among the lucky one to be fixed. ;)

hi, you have 2 versions of the mesh tools addon. Both are the same. 1 you would have downloaded from the blender artists thread and installed into Blender. You can delete this file. You must be using a nightly build, the mesh tools addon is also in addons contrib as a work in progress. It's based entirely off the not working mesh edit tools in release and will provide a replacement/base for updating that addon.
Please note: this addon is a work in progress and is not "perfect" with some small known glitches we will also be working on.
Thanks for the report. Closing as resolved.

Not a bug: The bug tracker is not a good place to ask such questions. The Blender Discord server would be a better place: DISCORD. You'll need a link to the plugin, at the very least, and the exact version of Blender you're using to get an answer. Most likely the plugin requires a certain version of Blender.

the new plugin i mean by it new sfm plugin

This is not an addon that ships with blender, please contact the author of the addon for support

when i import the f spy image in blender 2.8beta and then i press "z" to go to the wireframe, the image just disappears and the object is in wireframe mode

Please describe the issue more in depth, a step by step may help

Seems to have been fixed on 2019-05-18 build, so I'm closing it as resolved.

Thanks also to Maciej. You may not have got the right solution this time, but the willingness to help so promptly is appreciated.

Thanks for your help. Redownloaded the latest build and unzipped it with 7zip and that does seem to have solved the problem. Not something I would have thought of, so worth bearing in mind for the future as well. Again thanks.

Looks like unpacking the zip file has gone wrong, please try again with 7zip and make sure all files make it to the file system.

I think it is related to windows 10 update as it often destroy the GPU drivers. so if u can instal newest intel HD GPU drivers and try again? i know that blender 2.8 on linux with intel HD4000 works fine so. probably drivers issiue
