Dragging "Find result" window is very slow
Hello Fellow Notepad++ Users,
Could you please help me the the following problem I am having?
When I search inside a file for all occurences, the “Find result” window which is opened works very slowly when dragging it to different locations. Resizing works fine.
This was a problem on the older version I used (don’t remember which one), still occures on the lastest version.
My debug info:
Notepad++ v184.108.40.206 (64-bit)
Build time : Nov 13 2021 - 15:28:20
Path : C:\Program Files\Notepad++\notepad++.exe
Command Line :
Admin mode : ON
Local Conf mode : OFF
Cloud Config : OFF
OS Name : Windows 8 Single Language (64-bit)
OS Build : 9200.0
Current ANSI codepage : 1251
Plugins : mimeTools.dll NppConverter.dll NppExport.dll
There’s also was a similar issue on the Notepad++ issue tracker several years ago if it might help. I was about to open an issue there, but I’m not sure if this is Notepad++ code related or not. Maybe it’s just my hardware or something.
Since the vast majority of users don’t complain about this, and I’ve never seen such an issue, I am assuming you either have a large file open with complex syntax-highlighting going on, or some process (maybe Notepad++, maybe something else) is taking huge CPU usage. (Thanks for providing Debug Info: I don’t have to ask about plugins, since that gives the answer: you only have the default plugins, so the problem isn’t a weird plugin problem.)
There are other users who have reported getting unexpectedly large CPU usage in Notepad++, even without large file open or any weird/complicated plugins. Maybe you are seeing the same thing or a different symptom of the same problem. Unfortunately, developers have not been able to replicate the high CPU usage, so it’s probably some combination of esoteric exact circumstances with the combined Windows+Notepad++ environment of particular users.
Though for yours, I see you are running in Admin mode. You might want to see if it works more smoothly when you don’t use run-as-admin to launch Notepad++ (might have to turn off a checkbox in your shortcut properties)
Thank you for your response.
I don’t think this “slowness” caused by a huge CPU usage. I tried closing all the other apps, which may use more CPU power, closed every document in Notepad++ and opened a blank document. I wrote a word 4 times and did a search, and still the “Find result” window moves very slow on drag. I also tried running the Notepad++ without admin permissions and it doesn’t make it any smoother.
Just out of curiosity, I tried dragging the window with my touchpad, not the mouse (never tried this before) and I am surprised - the window moves just fine. I guess it might be caused by my mouse drivers or something, though I only encountered this problem in Notepad++ and nowhere else. I will try to see what I can do with this.
Idea from left-field: Are you using a gaming or other ultra high update rate mouse or driver setting which could be (ab)using the CPU during the move?
I have the same problem and I am pretty sure it started with the installation of an additional mouse control application. Unfortunately, the problem did not go away even after uninstalling this software. I assume it must have set settings in the registry that were not correctly reset to default. Since I don’t really change the layout of my npp environment, I can live with it otherwise I probably would have reinstalled Windows.
