positioning problem with european character

[JeanM]

Depuis le passage de Ubuntu-22.04 à 24-04, j'ai un problème de positionnement avec la souris à la suite d'un caractère spécifique européen (accentué par ex.) le curseur se retrouve en fin de ligne ou sur un espace inseccable plus loin.
Ça fini par énerver ! faisant des corrections et de la mise en forme de documents (Fr / Ru).
Mon soucis avec le presse-papier est résolu par un retour à X11 au lieu de Wayland.

Hi,
Since the upgrade from Ubuntu-22.04 to 24-04, I have a positioning problem with the mouse after a specific European character (accented for example) the cursor ends up at the end of the line or on a non-breaking space further.
It ends up annoying! making corrections and formatting documents (Fr / Ru).
My problem with the clipboard is solved by a return to X11 instead of Wayland.

Yes, Wayland is full of bugs, avoid it like the plague that it is.

[JeanM]

Je n'utilise plus Wayland mais ce problème de positionnement avec la souris est commun à X11 et à Wayland !

I no longer use Wayland but this positioning problem with the mouse is common to X11 and Wayland!

[kovidgoyal]

You need to describe your positioning problem more, I certainly cant replicate clicking with a mouse on an accented character causing the cursor to be positioned anywhere other than where I clicked.

I edit lots of french ebooks, and I've never noticed such a thing (calibre 7.17, debian stable, x11).

I would suspect another soft or utility interacting with the behavior of the mouse. I had once, for example, qstardict interacting with the clipboard of LibreOffice, and only with this one.

For testing purpose, try to unload every utility working in the background, or, better, create a new user and load the editor in it.

Par exemple :
<p class="Texte">À neuf heures du soir, l’honnête homme qui avait sauvé les jours de madame de*Fausse-Lendry vint l’arracher de la prison. «*Il était, dit-elle, avec un de ses camarades, humain comme lui. Ces deux braves gens me donnèrent le bras. La porte s’ouvre*; je me vois couverte de sabres sans pouvoir faire un mouvement. J’aperçois le sang qui coulait sous mes pas. Hélas*! sans doute mes pieds étaient couverts de son sang. je marchais sur des bras. des mains. sur celles qui avaient été l’appui des malheureux, qui m’avaient tant de fois secourue*!… O Dieu*! Dieu*! donnez-moi la force de supporter la douleur qui me déchire*!… Mes sauveurs demandent ma grâce, elle leur est accordée, je n’étais pas digne de recevoir une mort aussi glorieuse*<a id="retFtN2192" class="refNote" href="#FtN2192">2192</a>*!*»</p>

* Clic derrière le premier caractère de texte (À), le curseur va se positionner juste après "Madame de" car il y a un blanc insécable entre "de" et "Fausse-Lendry".
* Clic derrière le caractère "a accent circonflexe" (â) de "demandent ma grâce", le curseur va se positionner juste devant "glorieuse" qui est dans l'editeur en début de ligne suivante.

* Click behind the first text character (À), the cursor will be positioned just after "Madame de" because there is a non-breaking space between "de" and "Fausse-Lendry".

* Click behind the character "a circumflex accent" (â) of "demandent ma grâce", the cursor will be positioned just in front of "glorieuse" which is in the editor at the beginning of the next line.

Je viens de créer un nouvel utilisateur, et simplement ouvert le fichier epub en cour de création… Pas de problème de positionnement !!!
Dans mon environnement habituel je n'ai que Evolution et Firefox qui sont en tĉhe de fond occasionnement j'ai Gimp et/ou la capture d'écran. Ce qui est étonnant c'est que ce disfonctionnement est apparu après le passage de la 22.04 à la 24.04 d'Ubuntu.
I just created a new user, and simply opened the epub file being created... No positioning problem!!!
In my usual environment I only have Evolution and Firefox which are in the background task occasionally I have Gimp and/or the screen capture. What is surprising is that this malfunction appeared after the transition from 22.04 to 24.04 of Ubuntu.

I've never seen this with Irish or French, but I swapped from Ubuntu to Mint with Mate Desktop about 15 years ago though I was still also using Windows till the end of 2016.

[kovidgoyal]

Doesnt replicate for me clicking behind the a puts the cursor behind the a on both Wayland and X11

@Quoth
I never had this kind of problem before either. Before Ubuntu-16 I was using CentOS. It's apparently, for me, a configuration residue from Calibre or Gnome (or Python) that is causing problems in my user space. No problems with the Gedit replacement, nor with Firefox nor with Writer.

@kovidgoyal
As special stuff associated with Calibre, I only have dictionaries (fr, lat, es, pt, ru) and the contents of various user dictionaries… Since in a new user there is no problem of positioning maybe I can rename the directories used by calibre-editor… in this case what are they?
By the way about the "user dictionaries" is there a way to save them in an external file (or in an internal file to the current epub, although it is not standard) and restore (on another Linux or Windows computer).

Comme trucs particuliers associés à Calibre, je n'ai que des dictionnaires (fr, lat, es, pt, ru) et les contenus de divers dictionnaires utilisateurs… Puisque dans un nouvel utilisateur il n'y a pas ce soucis de positionnement peut-être puis-je renommer les répertoires utilisés par calibre-editor... dans ce cas quels sont-ils ?
D'ailleur à propos des "dictionnaires utilisateurs" y a-t-il un moyen de les sauvegarder dans un fichier externe (ou dans un fichier interne à l'epub en cours, bien que ce ne soit pas standard) et de restaurer (sur un autre ordinateur Linux ou Windows).

That confirms what I was suspecting, that some utility is intercepting events and modify the normal behavior of the mouse in calibre. It shall be one that starts automatically with your normal user's session, and not with the new user's one, look in your panel control to see which software are automatically loaded when starting the culprit session.

It's certainly not FF or GIMP or someother you start yourself,, but rather some soft waiting in the background for an event (stardict, screenshooter, some messenger soft, some special config for touchpad or keyboard, …).

Start them one by one in your new user's session until calibre begins to misbehave. Then, knowing which one it is, you may disable it in your normal session (maybe you'll need to logoff/login).

Another solution, more simple, is to use the new user as the default one, and during the personalization / fine-tuning of this new user's space, check at each step if calibre is still behaving normally.

Let us know if this solve the case, and which was the culprit if this apply.

Is it possible there's a newer mouse driver?

Mouse drivers are such a basic thing that I don't think they ever need upgrade.
Anyway, if it were the case, it would affect both users (the dysfunction vanishes if JeanM creates a new user).

So it could be something that's running at start. Is there a safe mode for Ubuntu?

Problème résolu !
Avec le passage à la 7.21 de Calibre, j'ai aussi viré le répertoire "~/.config/calibre". J'ai donc un Editeur-Calibre tout neuf, j'ai réinstallé les dictionnaires des différentes langues utilisées et recopié sauvagement une partie des dictionnaires perso…
Et mon problème de positionnement avec la souris semble avoir disparu !

Problem solved!
With the upgrade to Calibre 7.21, I also deleted the "~/.config/calibre" directory. So I have a brand new Calibre Editor, I reinstalled the dictionaries of the different languages ​​used and wildly copied some of the personal dictionaries...
And my mouse positioning problem seems to have disappeared!
Although there is no reason for this problem (perhaps the upgrade to a new version of Ubuntu and temporary use of Wayland instead of X11, and corruption of the configuration information) in any case, thank you very much for your help.
