This is very similar to
I hoped it would be gone with the upgrade from client version 4.3.x to 4.4.0, but alas - no.
Whenever a message is received on any channel, the Desktop Application UI freezes and does not react to user interaction any more.
The application is not completely frozen, though, and still reacts to network events - the “user is typing” real time indicator still works, and new messages will come in and be shown in the channels.
It’s just not possible to interact with the application for quite some time. After some minutes have passed since the last incoming message was received, interaction is possible again - until the next message is received…
It happens most of the time this way, even though I also had a situation where I could use the application normally. This was not reproducable, though, so I have no idea what needs to be done to be able to use the application normally and without UI freezes.
This basically renders the application totally unusuable.
Just start Mattermost Desktop Application 4.3.x or 4.4.0 Linux 64 Bit and try to use it.
The application’s GUI should not freeze for several minutes when a message is received.
See description above.

Who experiences similar problems, or who knows any workaround?
