Are there specific sizes we should be using?
I've tried 10x40, 12x48, 16x64 and 32x128. Some of the maximise icon is being trimmed and I've tried changing the painting margins in the titlebar options too to no avail.
This is using the 100% DPI on each.
I did have a problem with Edge Chromium but, after closing it and applying the theme again, as advised elsewhere on the forum, it worked but the maximise icon has the same cutoff problem.
