vktrace vulkan api trace
I'm building a Vulkan game, and I get a black window when I don't use
RADV_DEBUG=nohiz unless the window area is less than about 250k px^2. If I
resize the window to smaller than that, then it seems to work fine (except
maybe for some probably unrelated sRGB/gamma issues) even if it's really tall
and narrow or really wide and short.
It's possible I'm doing something wrong with the Vulkan API but I have not been
able to find where I'm messing up.
I'd guess that there is a memory allocation issue when allocating more than a
256k px depth buffer.
I have a RX 580 8GB.
I'm running on Ubuntu Linux 18.04 with kernel 4.15.0-34-generic
I'm using Mesa git from oibaf's ppa using version
18.3~git1809181930.c9dbe5~oibaf~b
I have Xorg version 1:7.7+19ubuntu7.1
I've attached a vktrace using LunarG's Vulkan SDK at version 1.1.77.0
I can reproduce the problem using just the vktrace, but for those who are
interested, my source code is available at
https://github.com/programmerjake/hashlife3d at commit
9d43f3ba82ba5d3d721a81e61da4dfed20a2926b
I am using SDL 2.0.8 built from source as until recently, SDL's vulkan bindings
were disabled in Debian's package.
