perasite,
Thank you for the screenshots. I see the white scrollbars appear when switching between files in the editor at my end though it switches to the original scrollbars once the other file is in focus.
I have filed it for further investigation with the dev team.
Regarding the Heap Status display problem, I have raised a bug for the dev team to fix it. We will keep you posted about the fixes for the reported problems.
Thank you for reporting. Sorry for inconvenience caused.
