Visual Studio Intellisense suggestions disappears immediately after coming up

Question

I am using Visual Studio Community and Visual GDB to code and debug STM32 projects.

The problem:

When I type something that is known to Intellisense, (path, variable or anything really), the suggestions come up briefly and then immediately disappear therafter. For that split second I can see that Intellisense has the correct suggestions, but TAB or ENTER does not work since the suggestions disappear very quickly.

Does anyone know how to fix this?

Thank you

I have the same issue, I noticed that it happens when the suggestion involves the context that is quite long beyond the screen. Here is how it look like:

---

|Function1(xxx,xx,xxxxx,xxx,xx,xxxxxxxxx, xxx) |Function2(xxx,xx) | | | |______________________________| Screen So if it has something like Function1 in that suggestion then it will instantly disappear after popup. The temporary solution is to separate the long function into 2 functions or more. I’m also looking for a better solution that might need some setting in the visual studio and make this long function working.

You might try to disable any extensions in Visual Studio.

I had the same problem, surfed around and read in some places that disabling extensions would work.

So I disabled them one by one and the problem was gone.
