Slow-down of gvim when upgrading from Buster to Bullseye

#1 Post by jaja »

Hello,
I upgraded from Buster to Bullseye and discovered that gvim (installed with package "vim-gtk") is substantially slower on Bullseye.
Online research (https://github.com/vim/vim/issues/1199) revealed that this slow-down issue is due to a difference in gtk2(fast) vs. gtk3(slow).

This slow-down issue has been on-going since 2016 across multiple versions of Linux.
Up until Buster, the work-around was to install the gtk2 version of vim/gvim.
Unfortunately, Bullseye dropped the gtk2 version.
Buster: "vim-gtk" points to "vim-gtk2"
Bullseye: "vim-gtk" points to "vim-gtk3" ("vim-gtk2" is not available in Bullseye)

I've tried the work-around (GDK_RENDERING=image) suggested in https://github.com/vim/vim/issues/1199.
It failed.

I've tried to locate a downloadable "vim-gtk2" package/tar for Bullseye, and failed.

I've begun investigating "neovim-qt" as a replacement.
But I'm having many issues converting my long-time gvim configuration to nvim-qt (example: mouse right-click does not work, prevents spelling correction).

Has anyone found a solution/work-around for this slow-down of gvim within Bullseye?

Thanks for the help.
