corruption in page 1 for big innodb tables in compressed format with mdb encryption

Attached mtr test results in following errors during restore:

[01] xtrabackup: Error: failed to read page after 10 retries. File ./test/t1.ibd seems to be corrupted.

[01] xtrabackup: Error: failed to copy datafile.

When I reduce number of rows - test most likely to succeed.
If remove row_format=compressed from table definition - then always suceeds
