Also mentioned in this thread was the blurry icon for the zoom tool
button.
I'm still seeing the fuzzy magnifier icon in the left-side toolbox as of
20967. I committed a change to line 377 of src/widgets/desktop-
widget.cpp
which chooses a different magnifier icon. If someone can't find a
better
way to fix the actual rasterizing/caching bug here, I'll add a brand new
dedicated icon for desktop-widget to use for "zoom-on-window-resize."
