Has anyone else using the flatpak of Signal-desktop recently notice it using 100% CPU? When first launching it there is no intensive CPU resources being used, but once I look at a conversation or start messaging it stays at 100% CPU in Usage app and in top as well.
I am using version 6.26.0
I am and I am not noticing any CPU slow downs at all.
I see the high CPU usage by Signal flatpak as well lately.
I don’t notice a slowdown either, although I do notice some higher temps on the phone. When I first run usage app it pegs the CPU between 2-6% before it jumps to 100% but top reads 116% CPU
From the 1980’s “A busy computer is a happy computer?”
Yes, but they weren’t running off battery. 
It seems that just using ctrl + Shift + C will exit any conversations and this will drop usage back to a normal levels.
I used to recommend Signal all the time for people, but honestly things keep getting worse with it, and I find all the constant updates just annoying. I think Matrix or XMPP are just much better solutions these days.
Does this work with the Librem 5 on-screen keyboard for you?
No it doesn’t seem to. I think a physical keyboard attached would work though. I’ll test it when I am my Mini X around again and let you know if no one else chimes in here.
For me, I just open the signal desktop when I need to say or receive something. Once I’m done, I always swipe it away, so I don’t think I’ve noticed the issue on the L5 yet as a result.
For a while the issue was resolved but now it looks like this bug has returned in version 6.30.1. When I open a conversation the CPU usage for one of the cores is either above 50% or nearly taking up the whole core at 95%.
Yep, always make sure you ctrl + shift + c out of all conversations. Or use Waydroid and Signal through there.
Is there a way to do this with the on screen keyboard?
I thought you could do it with the terminal OSKB but it doesn’t seem to work. Only works in convergence mode. Honestly I kind of hate using the desktop app on the L5. Running the actual client through waydroid is the way I’ve been going.
I would consider that or even Flare but I do make occasional audio calls through signal. Can waydroid be given access to the microphone?
At this time, I don’t believe so.
