Apologies if the question isn't succinct or globally useful.
I recently updated to Mavericks from Snow Leopard and brought over all of my toolchain. So, this is how my editor typically looks like:
My workflow typically involves heavy usage of the command-t plugin. For those unaware, it's a fuzzy file system searcher. When it's invoked it typically looks like this:
However, post Mavericks I have started getting these weird, hard to reproduce rendering bugs that are triggered with command-t. When the "fuzzy search selection 'drawer'" gets activated, occasionally the whole bits of the app will gain a black "highlight".
Case in point:
It's only triggered occasionally; right now it seems to correlate while fullscreened on my external monitor. Most of the time it works just fine and then it stings me, and I have yet to been able to discern any pattern to it.
It's quite frustrating; see for yourself:
Furthermore, it's also triggered with the ctrl-p plugin (another fuzzy file system searcher). It seems that whatever draws a "buffer that overlays your code buffers" is what triggers it, and is not specific to the command-t plugin.
This only started happening after I moved to Mavericks; my identical setup worked in an earlier MacVim snapshot in Snow Leopard.
I've posted this question in the hopes that this might seem recognizable to someone; I'm currently in the process of bisecting my bundle folder hoping that perhaps it's triggered by something else.
I have yet to try downgrading my MacVim snapshot (currently: 72; previous one was ~54). You can find my vimrc here, my .vim folder here and here is info on my macvim:
