Phantom keystrokes occur in RedHat 9.4

Hi,

Ous customer meet one touch function issue in RedHat 9.4
• The problem is that when the operating system starts and before opening the SW application, phantom keystrokes occur, that is, but nobody is physically pressing the touch screen.
• For a way of fixing it temporarily, disconnects and reconnects the touch screen by software tool and the problem disappears.
• The problem is very random, that is, so far they have only detected 5 problems in all the stores and it is detected when starting the machine.
However, the issue seems disappear after our customer upgrade RedHat to 9.5.
Did RedHat upgrade touch driver from 9.4 to 9.5?
Did RedHat fix some power management issue from 9.4 to 9.5?
