Shortcuts with remapped + or - key don't work on wayland (desktop)

[nidico]

The zoom-out shortcut (ctrl-minus) doesn't have any effect when running element-desktop 1.7.25 on wayland (which is possible since 1.7.25, see element-hq/element-web#15725). Zoom-in (ctrl-plus) and zoom-default (ctrl-0) do work. All three shortcuts work fine with element-desktop on xwayland.

System: Debian testing with sway (1.6)
Element version: 1.7.25 (desktop)

I've looked into this a bit more:

This only happens on my custom keyboard layout where - is remapped (through a custom xkb keymap) to the <BKSL> key which doesn't exist on US keyboards. If it's mapped to another key (or not at all) there isn't any issue. If plus is mapped to the <BKSL> key, ctrl-+ doesn't work, so this is definitely the culprit.

Also, there is no issue when using xwayland, so it seems like electron on wayland is using some other means to query key presses than xwayland.

I'll check further later and - if confirmed - report the findings on electron upstream.

I was wrong above (and tested with xwayland at some point). As soon as - or + are remapped to a non-default key (no matter to which key), shortcuts involving those keys don't work anymore. This does not happen if 0 is remapped (i.e. ctrl+0 still works).

I'm using X11 (not wayland) and, since today, I cannot use Ctrl++ as I'm used to, to zoom in.

I can use the workaround of clicking on the option in the menu bar, so it's not very critical, but I wonder why I was able to use this since forever and not since today.

• This is how the menu looks for the workaround:
  

• Other shortcuts such as Ctrl+- or Ctrl+0 work as expected.

I have the same issue as @yajo regardless of whether I use Electron's wayland or x11 (via xwayland) backend. This only happens with the plus key next to Enter, I was able to zoom in with Ctrl+NumpadPlus.
