After version 0.3.2, it does not work properly.

[dasu88]

I don't know why? After version 0.3.2, I can't run it properly anymore. First of all, the data is not available, and the settings page is fragmented, and the whole system is not working properly, but after returning to 0.3.1, it works fine.

[leandrosa81]

Sorry to hear you are having trouble with the deskband. It seems the control is just not refreshing itself. I will try to reproduce this problem here,. Do you mind telling your windows version, please?

[dasu88]

Here is my version：
Windows 10 Pro 20H2 19042.844

The problem is not only the screen refresh part, but also the chart data is not read correctly (As you can see in the above screenshot, all three parts of the CPU DISK NET are showing 0), and cause Windows operation stalls.

I'm sorry, I'm using online translation to convert to English, I hope you understand what I mean.

[leandrosa81]

It is very strange. Unfortunately, I am not able to reproduce this behavior on my machine.

It would help a lot if you could test if performance counters are working when this behaviour occurs (example: https://www.windowscentral.com/how-use-performance-monitor-windows-10).

You could also run it in visual studio, and see what is happening on the SystemWatchControl.UpdateGraphs() method (and if it is being called at all):

foreach (var ct in Counters)
{
    ct.Update();
}

[dasu88]

I tried the performance counter and it works fine. As for visual studio, I can't test it because I don't have the ability to do it.
It seems that there is a problem with the taskbar refresh. 0.3.1 is working fine, but later versions are not working correctly.
In addition, after the first installation, there will be a short period of normal operation, but after restarting the machine, the exception will appear and can not be used.

[leandrosa81]

So, I did some changes and released a new version (v0.3.4). Could you test it and see if it solves your problem?

Also, you talked about an exception, is there any error message? If yes, could you post here, please?

[dasu88]

Installed version 0.3.4 to test, the good news is that the data has been displayed properly, but the bad news is that there are still some abnormalities in the implementation. Including the toolbar icon does not appear properly, and will leave a residual image after closing the application, several times restart explorer.exe to test, there is an error, the system provides information as follows.

For the exception part, this is the issue. For the drawing issues I have also no idea what this might be.

The translation of the error is: Collection was modified; enumeration operation may not execute.

So the following line needs to have a .ToList() behind it, or change to another 'list' like implementation.

taskbar-monitor/TaskbarMonitor/SystemWatcherControl.cs

Line 398 in d622943

foreach (var item in info.History)

[KoalaBear84]

There is one thing I'm curious about. What happens when you press Win + Ctrl +Shift + B keys?

https://winaero.com/restart-video-driver-windows-10/

And what when you make a screenshot with PrintScreen ?

And do you have any other 'extensions' like PowerTools?

I have tried to restart video driver by pressing the shortcut key (press Win + Ctrl +Shift + B keys) while running, but only the screen flickers once without any improvement.
Also, I do have Microsoft PowerToys installed, but I have tried to remove it and re-test, same situation.
Other than that, I don't think I have any other PowerTools

[leandrosa81]

Thanks, @KoalaBear84. I wrote some code with locking mechanism, just need some more testing.

[leandrosa81]

So I just released yesterday version 0.3.5 that should solve this problem. Could you test it, please, @dasu88 ? Thank you and sorry for taking so long top replay since you posted this issue.

[dasu88]

Thank you for the correction. I have downloaded and installed this version when it was released.
In the tools section, it is currently showing normal. However, after installation, the toolbar is still displaying abnormally.
From the captures, we can find that the icon on the toolbar is normal before installation, but after installation, the newly opened application on the toolbar cannot display the normal icon, and the toolbar still exists after closing, so I feel there is a problem with the toolbar refresh.
