Not seeing that on my installation. I have 14 tabs and so far everything is behaving very well; I haven't yet found any bugs that directly affect me.
I'd suggest doing a direct download from GitHub and doing a re-install over the top of your current installation. If that doesn't fix it, save the data directory and do a clean install. If that works you can recopy the saved data back into the active data directory.
