"Packet Bytes" pane not showing ASCII bytes

asked 2020-11-04 13:17:41 +0000 gravatar image

Why am I not seeing the ASCII decode as shown on this help page:

I've right clicked and have "Show text based on packet ... as ASCII." Only one or a few of the ASCII bytes are decode. If I right click, select "Copy Bytes as Hex + ASCII Dump" and then paste into an editor, the decode is there.

(I'd paste a screen show but as a new user do not have enough points or something).

This works for me, I think we need a screenshot. Post it on a public share, e.g. Google Drive, DropBox etc. and post a link to it back here.

I have the same behavior when I locate the Wireshark window on a secondary monitor with windows' scaling enabled. Try to move the window to the primary monitor, this fixed it for me.

(Not an answer but rather than burying in comments)
To recreate (or a close facsimile thereof) on Win10:

  1. Change "Scale and layout" to 125%
  2. Open Wireshark
  3. Change "Scale and layout" back to 100%
  4. Select a packet to force redraw of packet bytes

There's a GitLab issue on this, right?

Yes. 3 or 4 with similar symptoms.

Could you add links to those issues here?
