In a Plasma Wayland session, there are numerous applications that sometimes run, sometimes don't with the following error : "Maximum number of clients reachedzsh: segmentation fault (core dumped)". Eg : dolphin-emu, Celestia, VLC... It seems to happen especially if Falkon is already launched. Plasma 5.13.2, Archlinux, Frameworks 5.47, Intel modesettings.
Looks like an Xwayland bug/missing setting?
Please report to Xwayland.
