I will confirm that I have the same symptoms. The screen is noisy. It seems that it is a graphics issue. It generates strange visual and crashes, usually within the first 30 seconds, especially if I move the mouse over it.
Here is the output when running TOR browser form the terminal:
user@host:~$ torbrowser Fontconfig warning: “/home/user/.tb/tor-browser/Browser/TorBrowser/Data/fontconfig/fonts.conf”, line 85: unknown element “blank” Fontconfig warning: “/home/user/.tb/tor-browser/Browser/TorBrowser/Data/fontconfig/fonts.conf”, line 85: unknown element “blank” Fontconfig warning: “/home/user/.tb/tor-browser/Browser/TorBrowser/Data/fontconfig/fonts.conf”, line 85: unknown element “blank” Fontconfig warning: “/home/user/.tb/tor-browser/Browser/TorBrowser/Data/fontconfig/fonts.conf”, line 85: unknown element “blank” Fontconfig warning: “/home/user/.tb/tor-browser/Browser/TorBrowser/Data/fontconfig/fonts.conf”, line 85: unknown element “blank” Fontconfig warning: “/home/user/.tb/tor-browser/Browser/TorBrowser/Data/fontconfig/fonts.conf”, line 85: unknown element “blank” Exiting due to channel error.

I cannot post to TOR browser as yet as I was not a registered user and am waiting for the confirmation of my account by the TOR admin.
Most of these terminal messages happened in earlier versions too. The ones present earlier are highly unlikely to be the cause now.
Most of these messages are generated by Tor Browser by The Tor Project. Only the last message Tor Browser ended with non-zero (error) exit code! is generated by Whonix’s torbrowser script. But it shouldn’t be used in this case.
During debug attempts, do not use torbrowser command (/usr/bin/torbrowser script) or the Tor Browser start menu entry because these are provided by Whonix ™ and are not the cause here.
A) Advanced users can try to start Tor Browser without the help of /usr/bin/torbrowser by Whonix ™, thereby bypassing that part of Whonix ™ Tor Browser integration. Tor Browser resides in folder ~/.tb/tor-browser. Therefore Tor Browser can be launched in Debugging Mode, which is a Tor Browser (not Whonix ™) feature. If that does not help…
As I mentioned in my earlier posts, I have test all possible combinations including downloading and installing or re-installing, virtualbox, Whonix and TOR-browser. All give me the same issue in Whonix.
I have no issue with TOR-browser on the same workstation outside of Whonix.
Somehow the issue is graphic orientated.
I am running the above on the latest Debian, I have two different monitors running in 4K. That may be the problem, perhaps.
It is totally unusable now as it crash within 30 seconds of loading and does create strange transient artefacts in the TOR-browser window that are very noticeable if I move the mouse cursor.
Thanks for your interest in this.
Problem is most likely the latest kernel version 5.10.0-15, it ruined all my VMs very badly…, just downgrade kernel on your host and try if this fixes your problem.
No panic. Nothing is broken. Just some rare condition has been hit.
Try again later. There is likely a solution for this problem.
Please see Whonix News, Whonix Blog and Whonix User Help Forum.
Please report this bug!
I think you are on the right track.
The little research I have done seems to indicate that too. The issue is between virtualbox and the kernel version 5.10.0-15.
I will not be able to check for sure until tomorrow (restarting my workstation is a huge job) when I will report the results here.
Thanks for that insight.
I am very sure the problem will be fixed after you downgrade the kernel on your debian host from 5.15 to 5.14. This version gave me tons of problems, didnt know what to do for days and had to reinstall all my VMs from the stratch.
I had segmentation fault errors in almost every app, broken update and upgrade(bizzare errors i have never seen before like “Hash Sum Mismatch” after apt update) , SIGSEGV errors in all chromium based browser, broken TOR, sdwdate and swap file creator on Gateway, all messengers broken/crashed and tons of other problems and errors. Now everything works good after kernel downgrade.
Dont reinstall your Workstation, first try to downgrade and check if problems on your WS are fixed.
Thanks anonimac. Rebooting my workstation with the previous kernel (5.14 instead of 5.15) did indeed fix the problem occurring. No need to make any changes to any VM or whatever. Just boot the workstation with the previous kernel.
Still don’t know what the problem is, but at least I have a working whonix until the issue does get resolved by virtualbox, linux kernel or whatever.
I had some of these isues when I updated to wayland and installed the hardened kernel, the xwayland server where flickering and I was having crashes in whonix.
Are you running Xorg?
Are you running the hardened kernel?
Kernel 5.15 does not cause any problems on the host but only on all VBox VMs. I tried to install kernel 5.15 on my VMs and so far as i can see it did not do any harm.
