(In reply to Roman from comment #24)

Running FreeBSD 12.2 on a Thinkpad T480 (i5-8250U CPU / UHD Graphics 620) using
the modesetting driver I had the same issue running Plasma 5 after upgrading to
mesa-libs-20.2.3.

However with ~/.drirc

<driconf>
    <device driver="iris">
        <application name="kwin_x11" executable="kwin_x11">
            <!-- https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=251836 -->
            <option name="glx_extension_override" value="-GLX_EXT_buffer_age"
/>
            <!-- https://gitlab.freedesktop.org/mesa/mesa/-/commit/580fbbb59a60
-->
            <option name="glx_disable_ext_buffer_age" value="true" />
        </application>
    </device>
</driconf>

Things work again. Thank you!
