Program run at startup hogs cpu?

[Bruce Steers <bsteers4@xxxxxxxxx>]

Here's a peculiar problem...
My launcher program Desktop-ish does something strange.

I add it to my startup by placing a launcher in ~/.config/autostart/
It looks like this...

[Desktop Entry]
Type=Application
Exec=/media/bonus/SSDiskspace/git/Desktop-ish/Desktop-ish.gambas -s
Hidden=false
Name=Desktop-ish

X-MATE-Autostart-Enabled=true
X-MATE-Autostart-Delay=3
X-GNOME-Autostart-Enabled=true
X-GNOME-Autostart-Delay=3

For some reason the program hogs the cpu , my fans blow hard and the
program uses 98% cpu.

If i close it then re-run it from the desktop icon it runs fine and does
not hog cpu.
If i do not launch it at startup and just run it from the icon it is okay.

But for some reason launching it from ~/.config/autostart/ makes something
go loop-de-loo.

Anyone seen anything like this before?
Know what might cause it,  know what to do?
gmail.txt archive is 600k so I cannot attach.
It's on git though...
git clone https://gitlab.com/bsteers4/desktop-ish.git
