Plasma crashes are not uncommon even with Intel graphics using a GPU driver in the mainline kernel. I don't see much "everybody's got different hardware" excuse with such a configuration; the GPU (and wifi, etc) drivers being in-kernel is 90% of why I bought this computer. Autohide panels is something Plasma seems to particularly struggle with. Sometimes the panel will start spazzing out, flickering and neither appearing nor disappearing, before finally crashing completely (and sometimes not coming back until I manually(!) restart plasma shell.)
