After logging in via GDM, the screen flashes and the cursor #310

I have a problem with the COSMIC environment starting after logging in, specifically the screen starts flickering from black to grey and the cursor also flickers. I got the output by using the command /usr/bin/cosmic-session in the tty3 environment. The output is here.

I have enabled Wayland in the GDM3 settings (/etc/gdm3/custom.conf) and I installed it using sudo apt install cosmic-*. The environment loads without any problems using only the /usr/bin/cosmic-session command in the running GNOME session, specifically, a window opens and COSMIC is loaded.

I tried it on Pop! OS 22.04 (in the virtual machine, specifically KVM). What could be the problem?

This is most likely the problem, you need hardware acceleration for cosmic-comp to work currently.

Try adding -vga qxl to your qemu command line or search for options to enable hardware acceleration for your virtual gpu, if you are using some GUI.

I switched to the video QXL from Virtio in virt-manager and now it works correctly. Thank you for your help!
