css - Why does Chrome cause this border / bleed around this image when using translate? -


see fiddle:

https://jsfiddle.net/uy6yhv4d/1/

i have img background-color: red set.

when rendered on page normally, without using transform, appears expected, no red border.

however, when trasform: translate positioning, red background "bleeds" edges, causing red border appear.

why happen?

the red border coming background-color: red;. found removing point values dimensions removed appearance of red border:

img {   height: 256px;   width: 200px;   position: absolute;   left: 50%;   top: 50%;   transform: translate(-50%, -50%);   background-color: red; }

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer ...
