Zotero 7: Duplication of right side pane after fast switching between tabs

mjthoraval · August 16, 2023

If I switch quickly between tabs, when I go back to the main library, I get a double right side pane. It seems to be happening when I try to load a large EPUB tab, but I did not make sufficient testing to verify this conclusively.

This is still happening in Zotero 7.0.0-beta.51+7c5600913 (64-bit).
Here is an easy way to reproduce:
1) Open a PDF file in the Zotero PDF Viewer
2) Go to the "My Library" tab
3) Quickly press Ctrl+Page Down - Ctrl+Page Up
--> When I get back to "My Library", the right-hand side pane is duplicated.

@mjthoraval Can you reproduce that on other operating systems like Linux or macOS?

I reproduced, and without using the quick press on keys, but by navigating several times with the mouse between "My Library" and tabs. It was enough to duplicate the right panel. But it takes several tries.
Edit: only PDFs

I can reproduce on Ubuntu 23.10.
I don't have a mac to test.

Actually, I have tested also on Windows 11 with a test account.
It seems that there is another component needed, probably related to memory being loaded or discarded. I had to open multiple PDF tabs, navigate between tabs, to finally trigger the problem.
