Description Eyal Rozenberg 2025-08-23 08:39:44 UTC 
The drop-down dialog buttons used in AutoFilters are not native UI widgets; we draw them - and we provide the graphic. It seems that graphic has not changed for the past 20 years, if not more, when screen resolution was half what it is typically these days.

Now, a more fundamental solution would probably be to use native widgets somehow (bug 163017) - but in the mean time, we should at least:

* Increase the resolution of the button images
* Apply a bit of anti-aliasing

and perhaps even:

* Make the images VCL-dependent to sort-of-emulate actual native widgets.

although just the first two would be an improvement.
