In process of time, the game launcher will sooner or later consume up all
available memory (I am attaching a useless screenshot).
The effect is well manifested with `Gw2-64.exe -verify` (although on the
current Wine you most likely will not be able to download the game client
completely for the same reason).

I have already finished bisecting and have done a few checks.
They led me to the fact that (I do not have programming skills to figure it out
for sure) maybe somewhere in "dlls/windowscodecs/decoder.c" or what it works
with, resources are not being released.
On that day, 8 patches were adopted aimed at working with windowscodecs, but
only the last eighth gives 
such an effect:
cd778e0b7f54cbbb9b7faae0dd6d25f826f54d6b good
1b37ac14a3e4a014c8440e691e9a2bbad9ba6575 bad

Please check it.
