Updated.
I have used Microsoft Office for many years and wanted to see how LibreOffice has come along in the meantime and it does not do as well as I would have hoped for on Windows. There is no included updater tool as in Firefox, so my old version stopped working completely (frozen UI) and the ancient hassle to download .exe files. Not a great start.
The dark mode switch causes buttons to be in the wrong colour looking like a buggy mess until a restart, but even then some of the icons and application colours were not applied correctly until I manually changed them so.
The ribbon view in Calc has its setting burger button on the right and it opens on another screen next to it?
What completely breaks it for me is the broken window resize. The ribbon tab titles are not rescaled and become inconveniently small. I then discovered the the compact grouped view and it made a better initial impression on me. Then I snapped the the window to the left and the UI is just cut off. Manually resizing it horizontally just breaks everything even more until the UI is empty and the rest is moved into the arrow.
The old school UI view meanwhile works and resizes, but it might be the slowest and laggiest UI on resize with goofy stretching I have seen in quite some time.
Also I really think the default theming and the 6 presets are questionable in fashion, but this is the least of its problems.
Wondering what happened to the development of LibreOffice? There are definitive improvements and probably there are even better under the hood changes, but why would such a large project ship such a bad experience? Was the core of the UI never touched the past 15 years? I have to to use an alternative.
EDIT: Resize runs better after forcing Skia Software renderer. Should not have to do that with an up to date AMD driver. Skia/Vulkan was the culprit. Disabling Skia leads to flicker on resize, so even more rendering bugs.
I'm of the opposite view on this. Been using Libre some years now but had to use Word for a bit on friend's computer --ewww! Nothing was where I expected it or even where I remembered it from years ago, the drawing program just sucks. I'm thinking people just get used to using what they've been using and feel that it's the 'correct' way. (I have that feeling too when I have to do anything on an iPhone)
Missing half the UI on resize is not something to get used, neither is the bad performance. Also the non-scaling ribbon titles are just a UI error. There is little debate to have.
