Screen Refresh Rate

[braham]

Afternoon everyone,

Once again, I am looking to the forum for some advice on an issue that may or may not be a problem.

We recently upgraded to QlikView 12.100.20100.11 (September 2025 SR1) and noticed that the rate in which the app refreshes the screen seems to be very slow. When opening Qlik desktop the app opens but is not maximised. Just clicking on the maximise button the screen does not refresh quickly or smoothly. A portion maximises and there is a definite pause after which the refreshes again and maximises. This is whithout any .qvw loaded.

It also feels that there is a delay between clicking on a selection and the app responding to the selection just made. While this pause is very short it does add up when making many selections.

I have tested this on our sever where we connect using a remote desktop connection as well as on my i7 laptop and both behave in a similar way.

On the server connection I have tied to reduce screen resolution, but this did not help.

Are there any other setting in Qlik Desktop that will help to improve this aspect of the performance?

Regards

Assuming you run QlikView Desktop from a shortcut (Start menu, desktop shortcut, or whatnot), you can set the properties of that shortcut to open in full window:

You might also want to see if using some of the compatibility settings for QV.exe helps, though I'm not sure they will. 

Otherwise, I'd try to run a packet monitor and see if you can isolate the reason it's taking a little longer on that side. If you can't, it's probably an issue with the desktop application itself and I'd perhaps try and get Qlik Support to look at it.

Take a look on the n release notes between the old and the new release if there were changes to the rendering engine or graphic settings because what you describes sounds like a kind of emulation or switching into a compatibility-mode between Qlik and the OS/graphic engine.

Thanks Marcus_sommer, appreciate your reply to my request. I can open as maximised, but I was really using that to demonstrate the slow screen response, which I think is affecting the overall performance. I used the startup as an example, as I do not believe this issue has anything to do with the underlying model. I check the compatibility settings, but those did not help. I also check the release notes and could not pick up anything that pertains to this issue. I have referred this to our network people to check the network settings. Unfortunately this issue is also present on my i7 laptop, so not confident any network issues will be found.

It seems not really related to a certain app or the data-set/data-model else that the UI itself delays the communication with the graphic engine ...

Nevertheless you may try it with a complete new app (just with a few dummy-data) or with complete new user-settings (renaming the existing settings.ini + making a backup) or with a new installation. Installing this release of a complete different machine (not the same type) could also provide some insights.

Thanks Marcus_sommer, I am going to uninstall on my laptop and then reinstall. As this issue seems to be on our server as well as the laptop. This will tell me if the issue due to the software being upgraded.
