This is not a problem with a specific file. This is also a problem in other discussions, users from the forum confirm this The problem occurs if most of the dynamic connection line is outside the window.

Hi @Mit

Please update your Visio to the latest version, such as: Version 2411 (Build 18227.20162).

I also suggest you modify the registry key for a check:

Registry Path: HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\Graphics

New DWORD: DisableHardwareAcceleration

Value: 1 (to disable hardware acceleration)

(Please note, serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.)

The version is the latest, manipulations with the registry do not help

This method does not work in builds 24, it worked in build 23. I had to install last year's build. Disable hardware acceleration for Visio in the next update.

Hi，

Thanks for your back.

Have you done any operation before this issue occurs, such as Windows updates?

In my test environment, this issue did not occur in the desktop clients of Visio Standard 2021 and Visio Plan 2.

In my opinion, this issue may also be related to DPI compatibility. What is the screen resolution you set?

Please locate to the Office root folder, C:\Program Files\Microsoft Office\root\Office16, find the Visio.exe, right click on it and click more options, choose "Properties", check whether there is "Compatibility" tab like following image.

If so, you may click "Change high DPI settings", then tick the box of "Use this setting to fix scaling problems for this program instead of the one in Settings" and "Override high DPI scaling behavior".

It didn't help. This problem appeared in one of the updates, previously there was an item in the visio parameters "Disable hardware acceleration of image processing" now it is not there, and it was at this moment that the problems began. There were no problems when this option was available.

To repeat this problem, most of the dynamic connecting line should be in the invisibility of the window and then try changing the zoom and you will see that at certain points the application slows down a lot even in an empty document with one dynamic line.

The problem is the hardware acceleration of image processing in the latest version, this item was removed from the parameters and it is with him that the problem is connected. In those versions of updates where this item is available, everything works fine. Please sort this out or disable hardware acceleration for Visio in the next update. A lot of people can't work properly in the app because of this.
