WORKAROUND: Setting the Intel driver's acceleration method to UXA rather than its default SNA *always* fixes the Flash problem, but causes a garbled login screen under LightDM that so far has no workaround. I also tried one possible fix for the default Intel SNA acceleration using the TearFree option. I created /etc/X11/xorg.conf.d/20-intel.conf with contents: Section "Device" Identifier "Intel Graphics" Driver "intel" Option "AccelMethod" "sna" Option "TearFree" "true" EndSection But this had no effect. [3.] Keywords (i.e., modules, networking, kernel): I'm a newbie hanging on by my fingernails here -- I have no idea about appropriate keywords.
