Photo of the problem
Sacha Willem's demos:
<a href="https://github.com/SaschaWillems/Vulkan">https://github.com/SaschaWillems/Vulkan</a>
Just got support for running in fullscreen, at monitor's native resolution:
<a href="https://github.com/SaschaWillems/Vulkan/issues/268">https://github.com/SaschaWillems/Vulkan/issues/268</a>
However, at least with Ubuntu 16.04 on SKL GT2,with latest git versions of
Vulkan loader & Mesa, frame content is slightly corrupted when tests are
running Vsynched, for example:
./raytracing -fullscreen -vsync
(By default the demos are currently vsynched in fullscreen, but it may change,
hence the use of -vsync option.)
When I tried running the demos without Vsync (= no "-vsync" option, MAILBOX
mode commented out from vulkanswapchain.hpp), i.e. X server will make a copy of
the frame content to screen, output looks fine. Screenshots (=copy of the
frame) also look fine.
I don't see it in all demos, but that could be a fluke. It was visible at
least in these:
- computecullandlod (very faintly)
- computenbody (very clearly)
- dynamic uniform buffers
- gears (occasionally)
- geometryshader
- indirectdraw
- multithreading
- particlefire (in fire)
- pushconstants
- raytracing (compute shader)
- specializationconstants
- texture
- texture3d
- texturearray
- texturecubemap (very faintly)
- texturemipmapgen (very faintly)</pre>
