I cannot get the 3.0 to run in my Linux desktop. All previous versions ok using normal binary install script.

I have tried a 'normal' overwrite install. It does install with no noticeable errors, but will not show up/open. My resource monitor shows "Calibre" and "Calibre-parallel" processes running.

I then did a reinstall of 2.85 and everything runs normal again.

Next I did the "isolated install" script and ran calibre from the command line per the instructions. Here are the errors:

A ctrl-c will terminate the process ok at this point.

Nothing unusual about my Linux install as far as "BadWindow" errors go, as far as I know. Is there a debug command that may help with this?

Thanks.
