I recently moved to emacs 26 and today I noticed a strange scrolling slowdown in certain Info nodes. It also occurs with emacs -q. If I go to Elisp info and try to scroll in the main index with page up/down then everything is fine and quick. If I go to Lists and then to Building Lists and there try to scroll down with page down, then the scrolling becomes slow, like it takes one second for emacs to scroll the page after pressing page down/up. The problem seems to occur only in info nodes where there are separate sections describing entities like functions in Building Lists: =C2=A0 =C2=A0 -- Function: cons object1 object2 =C2=A0 =C2=A0 This function is the most basic function for building new lis= t =C2=A0 =C2=A0 structure. =C2=A0It creates a new cons cell, making OBJECT1 t= he CAR, =C2=A0 =C2=A0 and OBJECT2 the CDR. =C2=A0It then returns the new cons cell.= =C2=A0The =C2=A0 =C2=A0 arguments OBJECT1 and OBJECT2 may be any Lisp objects, but mo= st =C2=A0 =C2=A0 often OBJECT2 is a list. In nodes with free flow text there is no problem with scrolling, so it's like info does something extra in entity describing nodes. It's 26.2 on Windows taken from the official GNU site: =C2=A0 GNU Emacs 26.2 (build 1, x86_64-w64-mingw32) of 2019-04-13 The problem also occurred with 26.1 =C2=A0I upgraded to 26.2. but it's the same there. Does anyone else experience this? Is this a known issue? =C2=A0
