[VKCTS1.3.8]likely case issue:dEQP-VK.dynamic_state.monolithic.line_width.static_dyna.list3_strip4 #464

Hi dear khronos developers,

I found this case mean to draw two lines, one vertex static line with width 3 and dynamic color (1,0,1,1), one horizontal dynamic line with width 4 and static color (0,1,0,1). When verifyResult(), case would check number of pixcels which matched dynamic color and static color. However, I found it failed because dynamicLineWidth was 2 and it supposed to be 4.

According to my test on /external/vulkancts/modules/vulkan/dynamic_state/vktDynamicStateLineWidthTests.cpp, when buildVertices(line327), dynamicVertCount was set to be 3, and dynamicVertCount 4. It was contrary to the original intention.

When I forced to exchange the mentioned two vertex count during vkcmdDraw(), case passed but draw dump was different form original one. I'm confused if I met a case issue.

Could you please help to check this fail issue? I'm looking forward to your reply!

Thanks!

I'm sorry to tell, it seemed to be my falut again, not case issue. This case set width for 2 lines correctly. But 128bpp format was not supported on my board.

Thanks.
