Hi Syam,
I don't have any gtk applications to test. But I have another
observations with file icons in Dolphin.
MSI and APK files do not have any icon. Not even the 'unknown' type
icon with a question mark.
Didn't notice this so far, but yes. I am confirming
that MSI files are
also "blank" and not containing any icon, not even "unknown type".
Seems
like we are suffering the same issue here.
Best regards,
Florian
