If it happens again, you can check for any error in DevTools (Debbug > Toogle DevTools)

Also you can try temporarily disabling the interpolation method, this was introduced in v1.1.0 and could be related

Those pic should be in original size without any interpolation, consider their size. Okay, I'll comment if got the bug again.

Hi, I just downloaded OpenComic and am receiving this issue on every page I try to view. I have Bleach comics downloaded and all of them appear as blank pages but have no issue with other cbz viewers. I tried disabling the interpolation but doesn't seem to be fixed. I downloaded a single One Piece cbz to see if maybe my files were bad, but am also seeing the same on most pages of the One Piece chapter. It looks like it is just saying the file is not found for each jpg page. Unfortunately can't attach a cbz but here is a link to the One Piece file.

This is what every page looks like:

Win10 with test build from #229 (comment)
Can't reproduce.

Interesting, I'm also on Win10, 22H2, build 19045. I downloaded the new test build and am still unable to see anything besides the first few pages and last few pages (same as previously for the One Piece chapter).

I have downloaded the example file and it appears that the error is caused by not reading correctly the UTF8 characters in the file names when using 7zip, fix 27c863b

Build with fix: https://mega.nz/file/rWhXjI5Q#GzGZRSkbUxvhnBB6Rt3JfZs8p_O8nVKQoFcRvybniyc

Once this build is installed, you will need to delete cache and temporary files from settings, as these would still have in cache the wrong file names from the previous build.

Amazing, works like a charm! Thanks so much for the quick turnaround! :)

Having the same issue but only with cbz files with really long filenames. Temporary fix is to rename and shorten the filenames of the folders inside the cbz (zip) files but it's not really a long term solution since it ruins my properly named and catalogued manga collection.

Closed as fixed and available in v1.3.0
