GNOME Bugzilla – Bug 747116
Cursor animations in Wayland backend are broken
Last modified: 2015-10-13 10:04:42 UTC
I'm not sure if this is reproducible on the Gnome compositor, but I can reproduce it reliably on Weston. It seems that the cursor animation timing on the Wayland backend is mostly broken. If you compare the speed of the animation of the, say, watch cursor, it's almost always faster then the one on the X11 backend. The speed of the cursor seems to be rather erratic too. If you launch ./test/testgtk and run the cursor test, every time you take the cursor in and out of proximity of the application surface, the speed is different.
I haven't been able to produce differences in animation speed under weston.
I don't see a speed difference, but there is clearly something wrong with animated cursors. Ever so often, I see a cursor image appear at the wrong coordinates, and the cursor is visibly flickering.
I found these steps to reproduce comment #2: 1. open nautilus (under wayland). I tested this on Fedora 23 Alpha 2. click on "Other locations" 3. move the mouse cursor As long as "Other locations" is loading, the mouse cursor wildly jumps around between the correct position and somewhere below (a bit left).
This was all fixed by commit 603ea3b. *** This bug has been marked as a duplicate of bug 755465 ***
