Before 22w19a the behavior of hovering over an item in the toolbar was smooth and did not have any issues. This issue makes it a bit rough when reading lores as the text randomly will jump for certain items depending on where you are in the inventory. It should be noted that I had to be in full screen to reproduce this issue.
22w18a:
[media]22w19a
[media]After this version, a change was made in the Screen#renderTooltipInternal class which included this new part of code (yarn parameter mappings).
if (y - j - 8 < 0) {
m = y + 8;
}
This seems to cause this issue.
This issue is more apparent when using a large GUI scale, tall tooltips will no longer be sticky to the top of the screen. In turn making these harder to read as they will be blocked by the bottom of the window.
