segfault on vulkan_backend.cpp : ClearFrameData #8328

Closed BlaiZephyr closed 2 weeks ago

BlaiZephyr commented 3 weeks ago

from discord:

i managed to crash the client by setting cl_refresh_rate and gfx_refresh_rate to 240 aswell as turning Vsync on

and then turning cl_refresh_rate and gfx_refresh_rate to 1000 and turning Vsync off

gdb outputted the following:

Could you start with dbg_gfx 3 and check if in the log the value for minimal swap image count changes when you toggle vsync?
