I don't remember who asked me about the #bitwigstudio #keyboard input issue that I mentioned when I was still on #manjaro.
Today, I came across crash logs indicating that "ibus-x11" can crash when Bitwig Studio is run on a #wayland session, resulting in Bitwig Studio losing keyboard input capability.
I did not have this problem on #archlinux anymore because #ibus is not installed by default and must be installed separately.
