Starting with the latest update (39.0.12) from this week, navigating to and from the Preview Window is very laggy.
The preview window doesn't refresh in real time, as it used to, and when you try to swith (alt-tab) to other windows it lags for some seconds before doing something.
Switching to other apps (alt-tab) from XD also results in the computer getting laggy for a few seconds.
This does not happen with any other Adobe apps, or any other apps in general.
I'm using Win10 with all the latest updates.
Hey there, I haven't experienced such issues myself. Just tested it and it seems smooth - preview window updates in real time as I add things to the artboard, and switching away from the preview window or Xd doesn't cause any lag with other programs.
Have you noticed whether it happens on larger files only, or does it happen even with a new blank file?
Do you have the latest video drivers?
I've been working with a pretty standard project (5-6 artboards), actually smaller than I usually work. The issues started today after I updated to the latest version.
I do have the latest video drivers.
The problems seems to be when switching from the preview window to other windows, even XD or other applications. I'm working too projects at the same time, which I normally do without any problems, and switching between both XD projects (using the task bar, or alt-tabbing) seems to cause a problem.
What size is your artboard?
Standard iPhone 6/7 from the XD presets.
And it seems it fixed it self, today it seems to be working fine. No lag, no nothing.
