--- Comment #18 from minion minion.procyk@gmail.com --- gave it another shot running this under kernel 4.18.2 using wine-4.0 stable w/o dxvk and i still get no window launching. I'm also not smart enough to dork around with ptrace under wine. I couldn't get any log lines that would help hint at the issue. Taking a guess i'd say we're not providing the correct buffer and/or offsets for PTRACE_POKEUSER
There are lots of type conversions being done like unsigned longs being passed to methods requiring signed longs and vice versa, longs being passed as int parameters. I have very little experience with C and C++ so I'm not sure if these are potential issues or not.
I'd be interested to see someone shed a little light on this. I dorked around for a bit with no change. Will be happy to help where i can.
