Hello everone, After upgrading to the latest snapshot I'm experiencing something similar to what's described here:
https://marc.info/?l=openbsd-bugs&m=166286641515911&w=2 I'm not sure if it's the same bug. In my case Xorg crashes (trace below). It happens with modesetting driver only, NOT with intel. It happens using fvwm2 while browsing its menus. Text desapears, the screen flashes a few times and eventually X crashes. I've build a new kernel activating *all* the options in this patch but that did NOT solve the issue. https://marc.info/?l=openbsd-bugs&m=166286799416220&w=2 # egdb -ex bt -batch /usr/xobj/xserver/hw/xfree86/Xorg Xorg.core [New process 532797] [New process 424021] [New process 348856] Core was generated by `Xorg'.
