Comment 110 for bug 1782984

I am also affected by this bug. I am running Linuxmint and Cinnamon just keeps crashing. Most of the times it is the result of clicking a few things and opening / closing guake at the same time.

Installing the proposed packages does not fix the problem though, I am still encountering frequent crashes:

(cinnamon:6385): Cogl-WARNING **: 15:11:23.728: Skipping layers 1..n of your pipeline since the first layer is sliced. We don't currently support any multi-texturing with sliced textures but assume layer 0 is the most important to keep
[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
cinnamon: ../../src/xcb_io.c:260: poll_for_event: Zusicherung »!xcb_xlib_threads_sequence_lost« nicht erfüllt.

I am running Linux Mint 20.2 Uma and have the libx11 packages installed with version 2:1.6.9-2ubuntu1.3

Edit: interestingly I can almost always reproduce the crash when unlocking the screen.

Edit2: I found a workaround: switching off high-dpi and reducing the resolution overall by a factor of 2 solved the Problem for me.
I am wondering if this is the wrong bug I am chasing.
