Currently we have a lot of unnecessary layers being created in the app,
which is extremely problematic on Windows when using Chrome, as it
deoptimises fonts rendering due to layers mismatch; chrome's algorithm
can't figure out if the layers won't resize or overlap so it creates a
lot of additional layers, which has a side effect of turning off
sub-pixel antialiasing on Windows.
This is a first step to improve the layering in the entire app.
