[Gimp-user] Large window size causes lag

[antiart <forums gimpusers com>]

Thanks a lot for your answer and workaround! I tried it and it works perfectly.
You also need both, the libpng15-15.dll and libpng16-16.dll (I simply copied the
libpng16-16.dll from 2.8.14 and renamed it to 15-15. Works well, so far). It's
probably a good idea to copy this one from 2.8.10, too.

I'm sure, this will help other people, too.

Before trying the dll-magic I also gave Gimp a high priority in he task manager
and put all my energy-saving-setting on high performance. This reduces the lag
pretty good.
Anyway, the dlls fix it completely.
