I was struggling to fix same symptoms in my corporate environment for this half year and found some causes.
When Zscaler turn on, below symptom occurs, right?
- Cannot scroll down in folder window due to popping back to the top
- Cannot select folder from task bar when opened multiple folders
- Cursor is often blinking
- CPU usage is higher than usual
It may be caused by proxy.pac confliction.
Is there any other softwares to push proxy to user computers?(e.g. GPO, VPN softwares)
If you configured forwarding profile in app as Tunnel (Proxy action : enforce) or TWLP mode or proxy enforced, issue will be continuously occurred.
Zscaler app always try to manage pac file in these modes.
If there is any other systems which is pushing proxy.pac to pc always, proxy.pac will be overwritten again and again in short term.
Determine which software is trying to push proxy to your pc or change Zscaler side setting not to enforce proxy to pc will be solution.
Hope this information will help you.
