Description Fabian Vogt 2021-01-26 08:21:44 UTC 
When trying to create a window rule for YaST, the prefilled generated conditions don't match.

Changing the window class match from "Exact match" to "Match substring" makes it work.

I believe this is because there are trailing spaces in WM_CLASS and WM_NAME for some reason:

WM_NAME(STRING) = "YaST2 - partitioner @ localhost.localdomain                                     "
_NET_WM_NAME(UTF8_STRING) = "YaST2 - partitioner @ localhost.localdomain                                     "
WM_CLASS(STRING) = "YaST2", "YaST2 - partitioner @ localhost.localdomain                                     "
