IDM 4.7.3 GUI configupdate.sh on RHEL 7.6
I have strange issue. When I run GUI configupdate.sh on RHEL server, utility is started as it should, but it looks like it has white text on white background with white borders... So whole window is white, there's only title visible ("NetIQ Configuration").
If I move mouse around I can see that cursor changes to different shapes (e.g. different mouse cursor to select drop down entry or to edit text). Even if I click mouse cursor in "invisible" text field and perform select-all and copy, I can see that there are real values (e.g. I get cn=uaadmin,ou=SA,o=data in clipboard), so configupdate is running as it should, there's just problem with color scheme.
So how could I change color scheme utility is using?
PS: I know I can run it in text mode, but I think it's much easier to run in in GUI...
