Pages jiggling in 'Pages' and in Canva
I am using iMac 2021 with Sonoma.
I use canva and pages to do intricate work and illustration.
The pages constantly jiggle making it almost impossible to work.
At first I thought it was the applications, but it must be the system...or/and the mouse?
Is there a different mouse that would help? Or mouse pad?
What is it?
I have had to abandon my old iMac which has served me so well and been reliable and stable...because canva no longer works on Yosemite.
But it's not working on Sonoma either! This is a jiggling mess!
Even as I write in this forum box, there is a bit of jiggling...
I find myself unconsciously placing two hands on the mouse sometimes to try and stabilise the system, which has no effect whatsoever!
I have no idea what actually to do!
I am feeling quite desperate as I am now beginning to dread doing my work.
any advice gratefully received!
TIA
