`initial size: 525312`

error I'm facing is on level 1 not on -1.


level:1, strategy: 0, dowrap: false
  required size: 553018  <- there is an issue
  required size: 283432
  required size: 526225  <- there is an issue
  required size: 301127
  required size: 409196
level:1, strategy: 0, dowrap: true
  required size: 553012  <- there is an issue
  required size: 44541
  required size: 414324
  required size: 289230
  required size: 176785


this is result for executing test case 2nd time:


level:1, strategy: 0, dowrap: false
  required size: 552979  <- there is an issue
  required size: 549979  <- there is an issue
  required size: 49738
  required size: 116661
  required size: 439574
level:1, strategy: 0, dowrap: true
  required size: 552973  <- there is an issue
  required size: 466730
  required size: 509795
  required size: 94907
  required size: 476173


All other levels are okay, this could be explained by Ilya's patch. What states that `hardware` compression will be used on level 1 and `software` compression will be used on all other levels.
