[Gimp-user] Large window size causes lag

Thanks! I copied those two files plus libpng15-15 as suggested from 2.8.10 and
replaced the relevant 2.8.14 versions. Appears to be working with no other
problems, although testing has been limited so far. I did get an odd error
message when starting up 2.8.14 for the first time after switching the files;
something like:
The procedure entry point cairo_mesh_pattern_begin_patch could not be located in
the dynamic link library C:\...\libpoppler-glib-8.dll

Since this wasn't a file I touched, I don't know if this was related. In any
case, I simply ok'd the error message and it all seemed to start up ok
otherwise.
