--- Comment #16 from Fabian Maurer dark.shadow4@web.de --- You need to compile perf 6.6 (or greater) yourself from https://github.com/torvalds/linux/tree/master/tools/perf Like in https://aur.archlinux.org/packages/perf-bfd
Then you need wine with debug symbols (e.g. self built). Run "perf record -g /home/fabian/Programming/Wine/wine/loader/wine DailyChthonicle.exe" After a while, ALT-F4 the program. In the same folder, run "perf script report gecko" Then tick the "Invert call stack" checkbox.
