Initially this issue looked similar to fractional scaling issues such as border rendering issues observed on windows previously but it seems to happen only on non-standard fractional UI scales such as 2.3, 2.7 and not on standard fractional scales supported on windows (1.25,1.75,2.25 ..) https://github.com/openjdk/jdk/pull/17484#pullrequestreview-1834275178.
