This looks very much like bug 324631 has come back. If I open an XFCE terminal or two I get nearly 100% CPU load to "X" and seconds of delay between key press and the character appearing. Close all XFCE terminals and use xterm instead and all is hunky dory. x11-libs/vte is at 0.28.1-r200 x11-terms/terminal is at 0.4.6 Reproducible: Always Steps to Reproduce: 1. Install XFCE terminal at latest version 2. Use it Actual Results: It's horribly slow and hogs the CPU Expected Results: Uses minimal CPU and responds fast
