c++ - How to troubleshoot vulkan blank screen? -

-

i went through lunarg 'drawcube' samples , incorporated code engine. when run, black screen, since black clear color. can change clear color different color , see it. but, geometry not render @ all. no errors or warnings generated.

my question is, can troubleshoot issue this?

renderdoc installs vulkan sdk (at least on windows), , frame debugger, similar pix/diagnostics, codexl , nsight. can give view of how graphics pipelines processing data.

you should enable validation layers (particularly vk_layer_lunarg_standard_validation), , install debug callback. if triggering 'warn' or 'error' messages, these indication of why not executing you'd expect.

-
Image
soapui doesn't seem dpi-aware , displays small on high dpi screen (tiny text , buttons). other applications running fine (screen resolution 3840 x 2160). version : soapui 5.1.2 os : windows 10 i have tried: configure soapui run "disable display scaling on high dpi settings" - parts of soapui looking bigger , don't display (image) changing resolution changing font size (preferences > editor settings > select font...) therefore assume, soapui pretends dpi-aware, not scale itself. have same issue? this workaround until developers round making version dpi-aware. step 1: add registry key hkey_local_machine\software\microsoft\windows\currentversion\sidebyside\preferexternalmanifest (dword) 1 step 2: add manifest file 'soapui-5.2.1.exe.manifest' in same directory 'soapui-5.2.1.exe' content of manifest file: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <assembly xml...
