Note: I've only been able to reproduce this on Windows (it works fine on Ubuntu 11.10 for me)

Now I have also tested on Ubuntu 11.04 and it also works fine without problem. Lately I have reported some bugs that only appear on Windows and do not appear on Ubuntu. Is there some Gtk# problem or something. Probably it would be nice to have the same Gtk# installed on both operating systems to know if the problem is Pinta problem or some out-of-reach bug. Is there still 2.12.9 Gtk# recommended (officially on pinta-project.org web page)?

The Mono downloads page has GTK# 2.12.10 available for download (http://www.go-mono.com/mono-downloads/download.html)

I'll try that later and see if it solves any of the issues.

+1 for me... thought what I saw was the image being duplicated. Which I suppose is exactly the same thing.

Just a quick update. Tested on Pinta 1.2 on Windows sp3 and problem persists (like described in bug report). But tested on
latest development on Ubuntu 11.10 and problem does not appear (like described in #2). So it looks like Windows problem.

Bumping in priority since this is a fairly easy issue to encounter.

It has something to do with zoom recentering code. If you zoom with mouse on the right side of the image it occurs, but not on the left side of the image. If you minimize to force a full redraw, you can see that the entire canvas is misplaced, it's not just a Invalidate issue.

Hey Jonathan,

I have Pinta 1.3 installed and so far it seems to be working correctly
now. Thanks for the follow up!

Thank you,

I have tested this problem one's more on Pinta 1.3 on Windows XP following bug description (top post) in this thread. Problem still persists. I have also tested this on latest Pinta development on Ubuntu 12.04 and it does not appear. But as stated in #2 and #3 it looks like this is a Windows only problem.

Johnathan Morlock, what is your operating system?

grofaty (grofaty) wrote :

Retested on Pinta v1.4 on Windows XP bug remains (see bug description in first post of this bug report).
Also tested in Pinta v1.4 on Ubuntu 12.04 and there is no problem.
So it looks like Windows specific.

P.S. I think we can lower importance of this bug to Medium or Low.

I'm in favour of leaving this as High priority, since it's a very easy bug to encounter and doesn't look very good

I can still reproduce the bug with pinta-1.5-preview-20130518 on Windows XP just like in the bug report.

grofaty (grofaty) wrote :

I can still reproduce with Pinta 1.6 prerelease build from source. I tested on Windows 7. Problem is Windows specific, it does not appear on Ubuntu 14.04.

Cameron, can you please do one of the two things: assign milestone to this "high" priority bug or lower the priority of bug. High priority bugs should have milestone defined.

On Ubuntu 14.04.3 LTS, and pinta 1.3-3ubuntu0.14.04.2, when I open image, make selection, copy, paste, and move around and zoom in, I get this:

forgot to say that as others described in the bug, once I paste and zoom in/out, the display gets corrupted and images/pixels go missing...

Im having this issue on Pinta 1.6, in Manjaro Linux XFCE x64 17.1.6, so, an Arch Linux based distro. After I've finished editing, zooming out produced the horrible result that I show on the screenshot attached to this post. The BIG problem is that the corrupted image gets saved as it is: corrupted. So I don't really like GIMP, and this bug also affects Xubuntu 16.04.4 and Linux Mint 18.3. Pity that after so much work (I'm not a designer, it's not easy for me) I have to delete the resulting file. Getting this bug only for zooming in or out seems pretty bad to me and having the bug marked as "Medium Importance" seems wrong. Uninstalling Pinta anyway because this bug is here since 2015 and nothing was done. It's 2018 I don't think I should expect any changes anytime soon. Many thanks for your time, have a great day.
