I have the same problem, this happens also when I receive any message. In dmesg I have this when the problem arise "WebKitWebProces[150032]: segfault at 10 ip 00007f2f91b7dbd9 sp 00007ffe2afdc380 error 4 in libwebkit2gtk-4.0.so.37.63.5[7f2f9189a000+21b3000] likely on CPU 1 (core 0, socket 0)"

In my case I'm in Fedora 38 in gnome-shell and I'm using the version 1.6.4 of whatsapp-for-linux

[benvantende]

Ahhh right. I checked dmesg too and I have:

So same

[nipnipj]

Same. Linux mint 21.2 here.

[joehuggans]

Also seeing this in Ubuntu 22.04.3 LTS with version 1.6.4 of this app from snap

Happens pretty randomly it seems, usually after minimising the window and restoring it, around 70% of the time.

[benvantende]

For me, it does not seem to have anything to do with any user action. It is pretty random. I only used Whatsapp-For-Linux now for maybe two months, but it seems like it might have to do with one of the packages it could be dependent on (I am no expert). From how I remember it, it was stable at first and at some point the blanks started to occur.

[xeco23]

It's probably related to webkit. However, changing Hardware Acceleration to On Demand in Preferences could solve it.

[ndias]

In my case doesn't matter if the Acceleration is on, off or on demand will always crash

That fixes it for me, it seems. No blank screens since changing that. Thanks, @eneshecan

same.

[benvantende]

So after having the On Demand setting for a day it makes the disconnection less likely to occur, but it still happens.

[xeco23]

See #330 please.

Take a look at this for a probable cause and workaround.
