LXDE-pi/lxpanel keeps an internal log file at $HOME/.cache/lxsession/LXDE-pi/run.log, and e.g. on RPi3 with official touchscreen the following log spam appears every time switching between windows:
The log file does not seem to be managed/size limited at all, and also it results in periodic disk writes, and user cannot control the logging at all.
