Thanks for reporting!

Does the file open correctly with other applications? For example, with File Roller.

You can check in the console if there is any error in OpenComic: Debug > Toggle DevTools > Console. You can also try running OpenComic from the terminal to see if any error appears there as well.

Does this happen with all files or only with a specific one? If it's a specific file, you can send me a sample to my email: oleguer.llopart.mora@gmail.com

App freeze and crash happens on all files during read, even the smallest files while opening.
Note: Files open correctly on other readers

It seems that GetVSyncParametersIfAvailable() may be the cause of the problem. I've seen several people reporting this error in the electron repository and in Chromium issues, it appears to be a Wayland-related issue.

Could you try launching OpenComic in the following ways?

./OpenComic-1.6.5.AppImage --disable-gpu

QT_QPA_PLATFORM=xcb ./OpenComic.AppImage --disable-gpu

You can also try this build, which includes a newer version of electron (v40.1.0 vs v37.8.0).

Bug persists in all launch variations (disabling gpu) and the recommended build too

You can try disabling thumbnail generation (Available in the new build I've attached) from the settings (Disable thumbnails (Show filenames)) and also disable image interpolation in the settings, to see if it's related to the sharp package.

You can also check which files OpenComic is extracting/writing by inspecting the folders /home/{username}/.cache/opencomic/tmp and /home/{username}/.cache/opencomic/cache. If you can't find them, you can print their locations from the console using tempFolder or cache.folder.

I've been testing and found that the package used in OpenComic for reading and writing json storage files (Such as the comics list, reading progress, etc.) can sometimes hang during I/O operations electron-userland/electron-json-storage#206. I'm not sure if this is the issue that you have reported, but I've replaced it with a custom implementation that no longer has this problem e6fb35b
