I am on Zorin 17.3, and will not update yet. Since the latest software updates, I have been having lock-ups with the mouse/cursor in my browser (Vivaldi), email (Betterbird) and also while trying to access the File manager from my bottom tray.
Firstly the browser: when clicking on the + sign for a new tab, nothing happens. This might be a Vivaldi issue, I don't yet know. Secondly; on two occasions while trying to attach files to an email, the email client has locked up completely and I've had to force a shutdown. Thirdly; while clicking on the File manager symbol in my bottom tray, the cursor changes from an arrow to a small hand, then insists on dragging the symbol out of the tray. I cannot shake it off and again have to crash the system to restart. I have never had these problems before; I've had mouse freezes a long time ago but the nature of these today is quite different. Any thoughts welcomed.
For Vivaldi and Betterbird: Are they installed as .deb or Flatpak? If Flatpak, I would suggest to try it with the .deb Versions.
Because of the Mouse Corsor: Is it a Third-Party Cursor Theme or the default one?
Vivaldi is the .deb package. Betterbird seems to be only available in Zorin as a Flatpak.
The mouse cursor must be the original one that was installed with Zorin; I'm not aware of having installed anything special for cursors; it's the sort of thing I never concern myself about.
I think I recall having a problem with the tar.xz archive that was downloaded from the Betterbird site. Therefore I think I may have installed the Flatpak within Zorin. But on the whole it has been running ok....until yesterday. Cannot reproduce the problem today, though.
just as a general user, vivaldi deb runs sweet as a browser... from may this year never encountered a prob.
I have been doing some testing. Although I couldnt reproduce the problem yesterday, it occurred again late last night, and this morning. On a whim, I shut off the hardware acceleration on the mouse, in "Settings". So far, after several hours, the problem has not reappeared in the email, the tray at bottom of screen, or the browser tabs. Even the silly little hand on the cursor has not come back. Fingers crossed for success....
