Comment 3 for bug 1731968

I confirm problems for GT640 and GT430.
Version 384.90-0ubuntu0.16.04.1 - works fine.
Version 384.90-0ubuntu0.16.04.2 - occasional crashes of applications.
Version 384.111-0ubuntu0.16.04.1 - crashes (same as previous).

Very often hangs KDE konsole. Checking by primitive testcase:
watch -n 1 konsole -e bash -c echo

After some seconds "konsole" crashes:
Application: Konsole (konsole), signal: Aborted
