After upgrade from version 2.50.8 to 2.50.9 the TREND objects created by HMI Designer are no longer transparent but have greyish background color. The chart then looks a bit ugly with fading colors.
Do you know how to revert it back to the original look, please?
Note: all runtime, studio and designer are upgraded to the newest version 2.50.9
Thanks and Regards,
Michal
