```bash
#!/bin/bash

#get some scrollback buffer via:
ls -laR / & jobpid="$!"; sleep 1; kill -9 "$jobpid"

echo '1. Now, start selecting by holding LMB and moving up past the window title which will (normally)cause it to scroll up'
echo '2. stop the above auto-scrolling by moving mouse into the window contents, before a new 'a' is echoed(by the below 'while'), while still holding LMB'
echo '3. keep holding LMB until a new 'a' line is echoed'
echo 'as soon as that happens, the entire selection is lost'
echo '(this issue only works if you scrolled at least once during selecting!)'

#echo something every 3 seconds(C-c to stop):
while true; do echo "a"; sleep 3; done

```
