"Show call tip" works very unreliable - sometimes works, sometimes not works, even if the first time it had worked then it stops after I've typed something or the second time I hit ctrl+shift+space

 :DThank you , can you remember before you use the show call tip , what did you input in the C::B .

In other words,what kind of the statement can make "show call tip" effect.

I wish I expressed clearly...Thank you.

Test code:

Code

#include <iostream>

using namespace std;
void abc(int aa, int bb)
{

}
int main()
{
    abc()
    cout << "Hello world!" << endl;
    return 0;
}
