Hover event delivery causes memory leak

Attached simple example crashes after a while and consumes lots of memory. This can be easily reproduced on Debian 11, On windows (I could not crash it ) but shows memory leak.

Steps to reproduce:

-Run  the application and bring the mouse on the application window

-Leave it running for couple of hours and observe crash. ( I left it running overnight)

Note: Very important, under no circumstance Mouse should move otherwise this will not crash.

Following tiny script if you run will show memory usage:

while true; do
TIMESTAMP=$(date '+%Y-%m-%d %H:%M:%S')
MEMORY=$(cat /proc/$(pgrep -f "HoverHandlerTestApp")/status | grep -E 'VmRSS' | awk '{print $2, $3}')
echo "$TIMESTAMP $MEMORY" | tee -a HoverHandler.txt --append
sleep 5
done
