dezza created an issue (vim/vim#18002)

Steps to reproduce

vim -g --clean -u NONE -U NONE

:hi
Very slow compared to regular vim. Pretty sure this is the case for all :messages as I've been noticing this lately.

I use wayland btw, not sure if this is a factor.

Expected behaviour

As fast as regular vim

Version of Vim

9.1.1591

Environment

Operating System: Linux (openSUSE Tumbleweed)

so does it happen in a X11 session? Does using -Y make a difference?

Actually yes, that solved it. Weird.

scrolling anything with syntax highlighting is also noticeably slow in gui wayland (kde)

And does -Y make it better?




no, gvim -Y is slow too

so it is not the clipboard code. good. Was it slow back when you had to use the GVIM_WAYLAND environment variable?

I donā€™t remember it being slow. But I rarely use Gvim on Debian.

You were right.


I apologize for the inconvenience. I will try to fix this by selecting the backend based on the WAYLAND_DISPLAY, DISPLAY vars and the given -Y -X

Well, today I opened gvim and it is as fast as terminal vim: :hi command, scrolling etc.


Idk, what is/was different from yesterday. šŸ¤·

I think gdk (gtk3) backend gets confused or fires both events when it has access to both X11 (XWAYLAND) and WAYLAND_DISPLAY something like that. https://docs.gtk.org/gdk3/func.set_allowed_backends.html


I'm also confident the -Y thing worked yesterday for me and I couldn't get that working on my new build.. There might be different states involved - either way.. Needs a fix.

@chrisbra I have concluded from experimenting tonight I think you should revert


patch 9.1.1585: Wayland: gvim still needs GVIM_ENABLE_WAYLAND

48a3b14


The wayland implementation is not ready to be standalone. I believe there is some unimplemented calls that hang or is dead ends with gdk_set_allowed_backends ("wayland,x11");


Therefore for now it should be opt-in as was the case before, until further improved.


I concluded the same thing when I tried to minimize the dependencies during the autoconf scripts on X11.


From the Display struct that is reused in Wayland to lots of other X11 functions are currently intertwined with Wayland and this is the problem, I believe.

Well, technically that may fix this issue, but that is because this patch always enables the wayland backend. But I assume the issue is then present again when using GVIM_ENABLE_WAYLAND is set. So we should rather fix the original problem. But this requires doing some profiling to find out what makes it so slow.

Sorry, github autocomplete must have set a random issue without me noticing, I edited it to #9639 which was original intention

Yes, true. Can you give a pointer how to make a profiling and I can attempt?

No conclusion yet, but here is some gprof I managed to create - not sure if it looks right, its the best I could produce without more experimenting;


slow.with_wayland.txt

slow.with_y_wayland.txt

last.known.good.1583.txt


It kind of looks like an allocation issue. Here's strace -f gvim just with the relevant "spamming" part when :hi is called
