Queue list in Winbox problem in 4.3

I’ve upgraded our backbone MT box, (AMD Athlon X2) to 4.3. I keep a winbox open remotely, showing Simple Queue list. Most of the entries never update unless you double-click on it. Seems like when I first open winbox, it’s updating, but it gets slower and slower. I also keep traffic graph of backbone interface, and it works just fine.

The same problem in version 4.10. How do I solve this?

I have same problems on my x86. First time I noticed it on 4.5 and then I upgraded it to 4.9 and still have that problem. Something is wrong with v.4.x globally.
