Right Click on Object / Variable Causes VS2017 to freeze

On regular occasions, right clicking on an object or variable to bring up the context menu causes VS2017 to freeze for 30s+. It eventually unfreezes itself and right clicking on the same object / variable then instantly brings up the menu.

I have tried disabling Resharper and I don't suffer this issue, it only occurs with Resharper is activated.

This doesn't occur every time and there doesn't seem to be any obvious pattern. I have also tried clearing Resharper cache and resetting all settings to factory settings.

I am using Resharper Version: 2018.2.1 and VS2017 15.6.7 (I can't upgrade to a newer version as I am using Cuda 9.1 and it doesn't support anything newer than this).



It would be great if you could collect and send us a performance trace which captures the lag - see https://resharper-support.jetbrains.com/hc/en-us/articles/210652849-Collect-Timeline-performance-snapshot-in-Visual-Studio about how to do that.

Thanks a lot!


Submitted as requested.


Edit : I have tried to submit several times, the files are uploaded, but ultimately results in a "Failed to upload some of the attachments" error.


Could you please upload the trace via https://uploads.services.jetbrains.com/ and let us know the exact name?


I'm not 100% sure what's happening here, but one of the functions on the call stack during a UI hang is Intel.CommonTools.IntelCommonPkg.GetFunctionAtCursor(). Do you by chance have any VS extension from Intel installed? If you do, please try disabling them temporarily and check if the problem goes away.


I have Intel Parallel Studio XE 2018 installed (which contains a package of Intel products). I have had versions of Intel Parallel Studio and and Resharper installed for past couple of years without issue and as stated previously when I suspend just Resharper I don't suffer the UI hang.

I will try to your suggestion and report back.


I am currently travelling so I haven't been able to do as much testing as I would have liked, but it appears that I when remove the Intel Parallel Studio integration, I don't been suffer the freezing. I have tried upgrading to XE 2019 that has just been released and the issue returns.

Therefore, I would tentatively conclude there is some issue between Resharper and Intel's VS integration that is causing this lock-up problem.

It is quite a pain for me, as really need the Intel integration for my current project and obviously I love ReSharper functionality.


Could you please also try disabling Visual Studio IntelliSense completely if it's an option for you? To do that set "Disable Database" to "True" in Tools | Options | Text Editor | C/C++ | Advanced | Browsing/Navigation. If this does not help then unfortunately you'll have to disable either the Intel extension or ReSharper.


Thanks for letting us know! If you miss some functionality from IntelilSense, please tell us, and we'll do our best to catch up.
