Jack X-run

Hey guys, I having a strange issue with jack, when I start Qjackctl with 256 frames/period it works fine, but when i change to 128, it starts popping Xruns with nothing connected or instantiated at all! The most strange part is that I don't even remember installing or changing anything these days and this started to happening out of nothing, it used to work fine with any frames/period. Here are some information:
