ALTPLL hangs on Ubuntu 18.04

Hi, I have installed Quartus 18.1 on Ubuntu 18.04. It starts but when I start MegaWizard for ALTPLL, the wizard hangs after I make one change in the main clock frequency. It consumes 99% of the CPU ...

Hi,

This happens for other IPs as well, so for MegaWizard in general.

It did not help to drag the window to the bottom right either.

System logs show that it waits on a file descriptor 6 and never gets a reply.

    @JPrig,

    Actually suggestion was

    "dragging the megawizard window bottom right corner"

    but you wrote

    "did not help to drag the window to the bottom right"

    do you see the difference?
