I can reproduce this with, Build-ID: 1:5.3.2~rc2-0ubuntu1~trusty1, CPU-Threads: 2; BS-Version: Linux 3.13; UI-Render: Standard; VCL: gtk2; Layout-Engine: neu

Very interesting because all other PageDown and PageUp moves jump to the correct rows.

Thank you for reporting the bug. I can confirm that the bug is present in
Build ID: 8c76dfe1284e211954c30f219b3a38dcdd82f8a0
CPU threads: 2; OS: Linux 4.4; UI render: default; VCL: gtk2; 

Additional info:
When current is A137 and A139 <PageDn> works ok.
The secuence <PageDn> <PageUp> works ok, except for cells A138 and A142, they return to cell top A136, instead of A137
