We're facing an issue with contact exports. They become displayed in the browsers as raw text.
We recently updated to php 7.1 and CiviCRM 5.25.0 but unfortunately and due to infrequent use of the export functionality we can't say if any of these changes directly led to the problem.
Does anybody has the slightest idea what could be causing this?

I'm stuck with this til today. I tried literally any detection method.
And exporting reports works.
When stracing apache for setting the header while exporting contacts or participants:
strace -fyp $(pgrep apache2|sed ':a;N;$!ba;s/\n/,/g') -s 30000 |& grep -i 'Content-Disposition:'
I get no results.
It would be too nice if anybody may shed some more light on this.
