--- Comment #18 from Aron Budea <[email protected]> ---
This can be reproduced using repo bibisect-win32-5.1, the memory use when
opening the start center with an empty profile is only ~16 MB before the
following commit, and ~90 MB afterwards (memory use depends on whether
translations are available, bibisect repos only include English language).

"enable opengl by default for Windows"

I added the following to <user profile>\registrymodifications.xcu to continue:
<item oor:path="/org.openoffice.Office.Common/VCL"><prop oor:name="UseOpenGL"
oor:op="fuse"><value>true</value></prop></item>

The increase from 16 -> 90 MB is with the following commit:

"remove all traces of old device code"

I'm inclined to believe OpenGL was simply blacklisted on my device before this.
I also believe the memory increase is due to the OpenGL feature, and trying to
bibisect this further is unnecessary, not to mention OpenGL isn't even used
anymore, though related pieces of code might be part of Skia now. 

Further increases in memory use might've piled onto this, but untangling why a
current daily build with all languages uses 245 MB (and for some reason 530 MB
with an empty profile) in the start center, will take further steps.
