Output corruption in CLion Follow

Console output corrupts (line beginning duplicated) sometimes. For example, following code:

#include <iostream>

int main() {
    for (int i = 1; i <= 20; i++) {
        for (int j = 1; j <= i; j++) {
            std::cout << j << " ";
        }
        std::cout << std::endl;
    }
    return 0;
}

Can produce such output:

Note this is not rearranged output - this is partial copy of line.
Error often breaks formatted (aligned) log output. In standart windows console same executable output works fine.
