The only bands Ive heard do this off the top of my head are girl goes to greenland and david attias (david attias much more slowcore but still super sad and emo and at times skramz). I think my friend once recommended old pride as a slowcore skramz band too but I may be wrong.

Some of the emo metalcore bands of the late 90s is the closest I can think of. Like poison the well and new day rising or some shit. Idk of any like straight skramz with bouncy riffs. Actually vein kinda buzzes that a little, also metalcore but they have some nu metal bounce as well as skramz chaos.
