--- Comment #4 from Ardith Metz <itgvk...@grr.la> ---
I've found the cause. 'kwin_ayland' binary is installed with 'CAP_SYS_NICE'
file capability[1] which blocks 'TMPDIR' inheritance across the runtime chain.
Removing that capability makes 'TMPDIR' correctly exported again.
This was introduced in[2] and caused env variables inheritance issue already
in[3].
I think the fix should be similar to the above - if TMPDIR var exist then pass
it explicitly to child processes
