intel with render nodes, tearfree and DRI3 and I run it with DRI_PRIME=1.

Because of bug 81834 I reverted f4b0ab7afd83c811329211eae8167c9bf238870c.

Now I get this crash in the "Effects Cave" demo of the unreal engine. More
rarely (?) I get bug 80880 instead/first. In other demos (perhaps less complex)
like TappyChicken I always get bug 80880 and never (?) this crash here:

0x00007ffff6a15859 in __memcpy_sse2_unaligned () from /usr/lib/libc.so.6


It seems to run for a few seconds, the music is playing, but the window
contents are black (it seems nothing at all is rendered, sometimes there are
white stripes that do not vanish until it crashes). Then it crashes with the
attached backtrace.

The "binary" struct seem to be always one of the same few. Others are:

binary = {code = 0x7fffb9ced270
"~\n\376\276\t\003\374\276\002\003\002\310\002\002\006\310\001\001", code_size
= 76, config = 0x7fffb9cf1a90 "(\260", config_size = 24, rodata = 0x0,
rodata_size = 0, disassembled = 0}

and

binary = {code = 0x7fffb9f85a10 "~\n\376\276\t", <incomplete sequence
\374\276>, code_size = 4160, config = 0x7fffb9e33840 "(\260", config_size = 24,
rodata = 0x0, rodata_size = 0, disassembled = 0}
