since updating SU last week, it runs slow/jerky on most external monitors. Especially zooming in and out with the mouse wheel… Works great on my M2 Powerbook monitor. Oddly today I tried connecting to a large Samsunk smart tv as an HDMI monitior and it worked ok with Classic Graphics engine not New Graphics Engine.
Im not sure what changed but my external monitor at work Asus and at home which worked great until this week, are not unuseable as I have to wait for 5-10 seconds for the monitor to catch up with the mouse. I tried both Graphics Engine settings, restarting, changing screen resolution, chaning refresh rates. Any help will be muchj appreciated.
