Note the failed to render icons.
Some of the icons render as grey squares, and when their functions are operational (such as the scrambled cut icon after selecting some texts) they show a very small and poorly visible icon.
This might likely have to do with my extremely high resolution desktop. It's greater than 1080p.
See attachments for incorrectly rendered icons.
I have uninstalled and reinstalled LibreOffice a couple times. I even purged data folder from appdata.
This one is already fixed. Thanks for filing, though!
