The strange behavior of the cursor in the Notepad + + window

Meta Chuh

i’m sorry if i upset you, it was not my intention.
its just very hard to get someone to look into an issue if it is difficult to reproduce, but i might have used the wrong words.

i’ve read at the “stuck at administrator” thread, that you have reinstalled windows 7 x64 instead of x32.
did it solve or improve your flickering cursor problem ?

It just happened again. I watched what was in the task manager (QTranslate, Google Chrome, Notepad ++, Everything)
closed QTranslate and the disappearance was gone, Notepad ++ was open at this time.
Maybe the reason is the QTranslate translator?

@andrecool-68 ,

If you close QTranslate and the problem goes away, then you should try a few more loops to confirm: start the translator, see if Notepad++ flicker comes back, then stop it again. If it’s highly repeatable that it flickers when QTranslator is running and does not flicker without the extra application, then it’s likely the way that QTranslator is interacting with Notepad++ – in which case, the issue might be in either application, or be a subtle interaction of settings in both.

That’s the only thing left to do …(;

sidenote to @PeterJones answer, which happened to be almost the same as the one i’ve just been typing for the last minutes but deleted it as i was slower due to trying to choose the phrases that can be translated unambiguously with qtranslator ;-) :

if you find out that qtranslate was the cause, please share it, and if you have time, please do not hesitate to help other community members if they experience a similar problem or any other problems that may interest you.

Perhaps this option makes the problem?
But I often need this option in the translator.

Since it seems to be QTranslate that’s causing Notepad++ to flicker:

You should update https://github.com/notepad-plus-plus/notepad-plus-plus/issues/5200 to indicate what you’ve learned
You might want to open a ticket with QTranslate – I think they’d probably have a vested interest in making their product work with as many GUI applications as possible. Besides, I think the default assumption will be “since Notepad++ only flickers when QTranslate is interfering, then it’s QTranslate’s problem, not NPP”. My guess is the QTranslate team would be able to debug whether it’s their problem, and if not, might know where to look for the problem on Notepad++ end.

It takes time to prove the guilt of QTranslate, perhaps this is a temporary coincidence.

you are a very good and thoughtful tester, i like 👍

When the cursor blinks again, I killed the “QTranslate” process in the task manager. This did not solve the problem.

PeterJones

That is unfortunate, but has not yet completely eliminated QTranslate (QT) as the culprit: QT may have put Notepad++ (NPP) into a state where it will continue to blink, even when QT is not running.

The next experiment I would suggest: After NPP has started blinking, and after killing QT, exit normally from all instances of NPP, then rerun NPP (without re-running QT). Is it blinking right away? If not, after hours of running NPP without QT, does it start blinking? If not, then it it is probably QT causing the issue If it does eventually blink even without QT actively running, there is one more action to completely eliminate QT: do a reboot, and make sure QT is not run at all after the reboot (if it automatically runs after a reboot, you’ll need to disable that feature temporarily), and run NPP; if NPP starts blinking after a reboot when QT has not been run at all, then QT cannot be the culprit.

If you are convinced that QT is not the culprit, it’s time for more debugging. Skimming back through the history, I see earlier that you say you only use the portable version… but you never really answered whether you have any plugins (the portable version can still use plugins). It may be that you have a plugin that is interfering. Showing us the result of the ?-menu, Debug Info, Copy debug info into clipboard will show if there are any plugins. Also, you can run notepad++.exe -noPlugin to ensure that you aren’t loading plugins.

This seems similar to https://github.com/notepad-plus-plus/notepad-plus-plus/issues/2010 which was fixed in https://github.com/notepad-plus-plus/notepad-plus-plus/pull/2952. Looks like there are some other cases need to be checked.

SinghRajenM

There is work around to this problem. Once mouse pointer is changed to cursor everywhere (specially on menu), then clicking on editable area resolves this issue.

Moreover, this issue can be reproduced easily with the file attached on bug https://github.com/notepad-plus-plus/notepad-plus-plus/issues/5194.

Steps:

Open the above file in the Npp.
Try to goto end of file (Bad allocation error will occur).
Now close Npp and start again.
As soon you start npp, bad allocation error will occur again. Keep on clicking on “OK” button on the messagebox.
Once all the messageboxes are closed, the reported error can be seen.

@SinghRajenM

thanks for your ideas.

i’m trying to reproduce the flicker using your git post but i can’t get the bad allocation error with the file at https://github.com/notepad-plus-plus/notepad-plus-plus/issues/5194.
i can scroll down to the end without any issues.

i’ve tried in np++ 7.5.5 and 7.6.2 x86 with dspellcheck 1.4.6 and 1.4.9
do i need any special setting in dspellcheck to trigger this error ?

@andrecool-68

what happens if you activate multi line tab bar ?
(settings > preferences > general > tab bar >>> multi-line)

are there any changes depending on how many tabs are open ?
(answer: no … i’ve just answered this question myself by rewatching your videos ;-) )

QTranslate Portable Version, There is nothing in autoload, not even antivirus. I myself can’t call that hallucination, it happens by itself.
And I’m glad to know that I’m not crazy. Such problems were with others! Just no one knows how to fix this problem.
I have this editor for many years, and I do not want to part with it.

Notepad++ v7.6.2 (64-bit)
Build time : Jan 1 2019 - 00:02:38

PeterJones

If it’s not the QTranslate, then my next best guess is it’s a variant of what @SinghRajenM described – hopefully, he can chime in more and help you run experiments regarding that possibility. If it’s not that, then you’ve got a few plugins, some of which I have no experience with, so my -noPlugins experiment would be what I tried next.

andrecool-68

I did not understand what error should appear pi these actions.

SinghRajenM

@Meta-Chuh, I reproduced flicker error with npp V7.6.1. while the bad allocation error was reproduced with DSpellCheck V1.4.8.

@andrecool-68 the error looks like screenshot added at https://github.com/notepad-plus-plus/notepad-plus-plus/pull/5212
