jtop crash on Memory tab when using gnome-terminal

[jankais3r]

Describe the bug After upgrading to Jetpack 4.5 [L4T 32.5.0], jtop crashes every time I try to switch to the Memory tab. It only happens when running in GNOME Terminal - over SSH or in LXTerminal it doesn't crash.

To Reproduce Steps to reproduce the behavior:

1. Open GNOME Terminal
2. Run jtop
3. Switch to the Memory tab
4. See error

Hi @jankais3r , Can you try to enlarge the window? I think this bug is related to the window size.

[jankais3r]

Confirmed, that was it. I initially tried it in a 640x480 VNC session, but once I increased the resolution, the problem went away. Feel free to close the issue, although having a graceful handling of this situation might be useful as 640x480 is the default resolution of VNC on L4T.

I will fix this issue soon. I close this issue, is a duplicate of #75
