Subject: Would it be worthwhile to set TearFree on by default for radeon and amdgpu in Xenocara?

Hello misc@ (also sent to tech@)

A while back, the modesetting driver in Xenocara got the TearFree option
set to "on" by default:

https://marc.info/?l=openbsd-cvs&m=174949311406685&w=2

I think it may be worthwhile to do the same for amdgpu and radeon
users. I have vision issues that make me nauseous when there's any
level of screen tearing on my machine. It would be nice to not have to
manually override the default in Xenocara for these drivers. One more
sane default like this can go a long way for a fair number of users I
think.

FWIW, for now, I use this xorg.conf to solve my issue.

    ~ $ cat /etc/X11/xorg.conf 
    Section "Device"
        Identifier "WX3100"
        Driver "amdgpu"
        BusID "PCI:1:0:0"
        Option "TearFree" "true"
    EndSection

Thanks,

May your day go well...
