malloc error when opening on-screen keyboard

[unkbar]

When in 2TONE, DIGITAL, RTTY, or PSK32 mode, pressing the KBD button in the bottom right corner causes the application to exit with the following error: *Error: malloc failed on waterfall buffer

This was captured by running /home/pi/sbitx from a shell window. The problem also occurs after starting sbitx normally from the panel at the top of the GUI.

It appears to be linked to the display size. When running sbitx remotely with VNC the error occurs at the default resolution BUT when I use the W9JES sBITX Toolbox "SCREEN RESIZER" to change screen to to MEDIUM or LARGE size the error does NOT occur.

This was observed on a new factory-assembled sBitx SN:0880 bought at Hamvention , running sbitx V3.02
