Thank you!

Yay for new versions! 😊

I’ve discovered a display glitch in 26.1. Zooming the view under certain conditions produces a bumping effect rather than the expected smooth zoom.

Conditions:
An object must be selected and centred
Vertical viewport offset ≠ 0 (bigger is better to notice the effect)

Appears when using repeated presses of page up/down to zoom in/out. Holding the key down or using the mouse wheel to zoom doesn’t show the effect.

When page up/down key is pressed, the starfield experiences a small “bump” up and down in addition to the expected zoom. The bump seems proportional to the offset – 1° produces no visible bump, 50° produces a big one (I usually use -20° and the bump is visible).

See this video for a demo (the glitch appears at 21 seconds): https://cleanshot.com/share/W0WsdnwG
The video has 6 sections, each with a few presses of page up/down to zoom in/out:
00:00 No object selected / Vertical viewport offset 0° (no bumping visible)
00:06 Object is selected / Vertical viewport offset 0° (no bumping visible)
00:11 No object selected / Vertical viewport offset 20° (no bumping visible)
00:17 Object is selected / Vertical viewport offset 20° (no bumping visible)
00:21 Object is centred / Object is selected / Vertical viewport offset 20° (bumping visible)
00:29 Object is centred / Object is selected / Vertical viewport offset 50° (more bumping visible)
