Renderer stops working and shows black screen after some time

[link2xt]

In the console I see

Error sending from webFrameMain:  Error: Render frame was disposed before WebFrameMain could be accessed
    at WebFrameMain.send (node:electron/js2c/browser_init:2:94617)
    at WebContents.send (node:electron/js2c/browser_init:2:79767)
    at Object.send (/home/user/src/deltachat/deltachat-desktop/src/main/windows/main.ts:172:24)
    at AccountManager.<anonymous> (/home/user/src/deltachat/deltachat-desktop/src/main/deltachat/controller.ts:99:18)

Menu is still displayed, I can click File->Settings to get more errors like this.

This I select Quit and it shutdowns cleanly:

523.8s [i]main/index: Starting app shutdown process
523.8s [D]main/index: mainWindow.window.on('close')
523.9s [i]main/state: Saving state to /home/user/.config/DeltaChat/config.json
524.4s [i]main/index: Quitting now. Bye.

This is on Linux with Wayland (river wayland compositor).

There are also errors like this:

[1745749:1216/152348.415128:ERROR:gl_surface_presentation_helper.cc(260)] GetVSyncParametersIfAvailable() failed for 2 times!

There are a lot of issues like this with Electron apps:

Maybe this is related to Electron running in Xwayland rather than native wayland? Should we add --enable-features=UseOzonePlatform --ozone-platform-hint=auto to electron command so it runs natively on Wayland rather than via Xwayland? With this option killall -9 Xwayland does not kill the app, and without it by default apparently it runs via Xorg.

With native wayland mode there are no issues so far.

With native wayland mode there are no issues so far.

in flatpak there is a display scaling issue where it gets blurry, I guess it also exists outside of flatpak but haven't tried personally: https://github.com/flathub/chat.delta.desktop/pull/124#issuecomment-1962575127

• --enable-features=UseOzonePlatform - this is the default in newer chromium / electron versions, so not needed anymore
• --ozone-platform-hint=auto - this might still make sense, there is a pr to make it a default on https://github.com/flathub/chat.delta.desktop/pull/124 (which I included in the 1.44 update pr: https://github.com/flathub/chat.delta.desktop/pull/125)

Also we updated electron recently, does this still happen on the newer versions?

let's reopen this when it happens again
