When the cursor transitions from link mode to normal, it moves to the left for an instant before being displayed in the correct location.Mouse cursor flickers when changing states using the Discrete GPU - YouTube.
I've reported this to Apple via their Feedback Reporter:įB8452310 - GPU causes mouse cursor glitch on 16" MacBook Pro Middle-clicking a link also produces a similar jitter. On link-heavy pages, moving the mouse across the screen results in a dizzying blur of pointer motion.
Here is an iPhone video of my Mac's screen demonstrating the issue: When I create a screen recording via QuickTime, the mouse glitch is not visible in the recording. Arrow pointer then flashes back to its true position, pointing at the same pixels that the hyperlink glove was originally pointing.Arrow pointer initially flashes at the "top left" position of the mouse bounding box for 1 frame.Move mouse pointer off the hyperlink so that cursor changes to the arrow pointer.It is unrelated to input device or tracking speed. The issue has been tested and occurs using the onboard laptop Trackpad, external Magic Trackpad, and an IBM TrackPoint. If "Automatic graphics switching" is toggled off, it will reproduce on the MacBook's display.Any time an external display is connected.This occurs 100% of the time when the discrete GPU is active. I don't believe this computer used to have this problem, prior to upgrading to Catalina. I now notice I'm also experiencing it on a Mid 2015 15" MacBook Pro running Catalina with the AMD Radeon R9 M370X 2 GB. This is in macOS 10.15 Catalina on my new 16" MacBook Pro with AMD Radeon Pro 5500M 8 GB GPU, provided by work and with a variety of software installed. It also occurs in other non-hyperlink instances of the mouse cursor changing, such as hovering over the drag handle when resizing Finder columns.Įvery time the mouse transitions from the hyperlink pointer to the arrow pointer, the arrow pointer briefly visibly flashes in the wrong position before correcting itself.
I'm experiencing a jittery/buggy/flickering mouse cursor when moving my mouse over hyperlinks.
