Mousepad: Issue zooming text back in after having reached a certain zoom out level

Hi all, this is my first topic, so please excuse potentially missing details and/or incorrect formatting etc., but please let me know about it, so that I can improve my future posts. :slightly_smiling_face:

As the topic already says, when writing random text in mousepad and pressing Ctrl+- several times, the text gets zoomed out (in my case, doing so 3 times leads to the minimum zoom level). After having done so, pressing Ctrl++ has no effect anymore and the text stays unreadably small. The same behavior occurs when using Ctrl+ mouse scroll down and again Ctrl+ mouse scroll up.

More details in brief:

  • mousepad version affected: 0.5.2
  • System default monospace font is set to Liberation Mono Regular 9
  • Mousepad is configured to use the system default font
  • Switching the default font to DejaVu Sans Mono Book 9 doesn’t change the behavior

My inxi output is as follows:

I could reproduce the described behavior on two further installations (1 native, 1 VM) that are based on different installation ISOs (which I can’t name exactly anymore, sorry). The cross-check in a VM with vanilla Arch installation resulted in Arch not having this issue. Did I configure something incorrectly?

[Edit, 2021-03-07]: Added mousepad version affected (-> 0.5.2)

Indeed, same issue as you, but i have to zoom out 4 times to be stucked.
I have the same issue with the newest SparkyLinux as well as Manjaro, i have checked in the VM few minutes ago.
In both cases, this is Mousepad 0.5.2, so i guess it’s related to Mousepad itself

Thanks for double-checking.
Oh, I forgot to mention that I’m using mousepad version 0.5.2 as well. :hushed: I’ll enhance my post accordingly.

As mentioned in my post, my Arch system does not have this issue, so it cannot be a mousepad bug, but quite interesting that SparkyLinux is affected as well. :thinking:

I have just updated Mousepad to version 0.5.3 from Arch repo : Arch Linux - mousepad 0.5.5-2 (x86_64)

I do not have this zoom issue anymore :slight_smile:
It was a Mousepad issue i guess, on Arch repo, version 0.5.3 exists for more than one week, that’s why you can’t reproduce on your Arch system

Many thanks for having checked the issue again in this newer version, and of course you’re right. I had already version 0.5.3 installed in Arch and thereby actually compared different versions. Sorry for the confusion. That was my mistake.

I’ll mark your post as solution. :slightly_smiling_face:
