In my xorg.conf's ServerFlags section I have: Option "MaxClients" "512" This works fine with x11-base/xorg-server-1.20.* With x11-base/xorg-server-21*, X clients start getting BadIDChoice errors once there are ~256 connections: $ for A in $(seq 1 300) ; do xterm & sleep 0.2 ; done ... [212] 17654 $ X Error of failed request: BadIDChoice (invalid resource ID chosen for this connection) Major opcode of failed request: 55 (X_CreateGC) Resource id in failed request: 0x20000000 Serial number of failed request: 3 Current serial number in output stream: 7 At that point, according to xrestop, there were 256 connections (with the balance taken up by window manager, other apps, etc.). Downgrading back to x11-base/xorg-server-1.20.* avoids the error. This happened the first time I tried xorg-server-21* some months ago. I thought maybe https://bugs.gentoo.org/830482 was related, so I tried again now that that is fixed, but the same problem occurs.
I've reproduced this with the Intel drivers too. It looks like https://gitlab.freedesktop.org/xorg/xserver/-/issues/1310 is the report upstream.
I've included some of the details here upstream: https://gitlab.freedesktop.org/xorg/xserver/-/issues/1310#note_1464002
