Issue Tracking Info

• I understand that work is tracked outside of Github. A PR will be linked to this issue should one be opened to address it, but Bitwarden doesn't use fields like "assigned", "milestone", or "project" to track progress.

Hello everybody,

This happened to me as well. I can even unlock my vault, but it's all just black. One interesting tidbit is, that the Todoist Desktop application has the same issue. I suspect there is some weird interaction between Flatpak, Electron and Wayland. I use the Flatpak com.bitwarden.desktop 2023.10.0

System info:

Operating System: Fedora Linux 38
KDE Plasma Version: 5.27.8
KDE Frameworks Version: 5.110.0
Qt Version: 5.15.11
Kernel Version: 6.5.9-200.fc38.x86_64 (64-bit)
Graphics Platform: Wayland
Processors: 12 × Intel® Core™ i7-5930K CPU @ 3.50GHz
Memory: 15.5 GiB of RAM
Graphics Processor: AMD Radeon RX 7900 XTX
Manufacturer: MSI
Product Name: MS-7A20
System Version: 1.0

What I've already tried unsuccessfully:

• Turning it off and on again (whole system).
• Removing and reinstalling the flatpak
• Different combinations of access to windowing systems in the flatpak confinement settings
• Setting the system theme to white (yeiks, my eyes)
• Switching back to X11

Workarounds I've found:

Using the rpm, I can use Bitwarden just fine, in dark or light mode. I also tried downgrading the flatpak. The last commit ID which works for me is: d484e7474b902fb30a39acafd054b2027cf6ec4acca65266319e517a9fdce902, which is Bitwarden-2023.9.2.

If you are using flatpak, try downgrading using the following command:

sudo flatpak update --commit=d484e7474b902fb30a39acafd054b2027cf6ec4acca65266319e517a9fdce902 com.bitwarden.desktop

Commits can be listed using:

sudo flatpak remote-info --log flathub com.bitwarden.desktop

Please note that I'm not a Bitwarden dev, downgrading may or may not have security implications. The release notes do not say anything obvious about security fixes. Use your own judgement.

Same issue on Fedora 38, in dark + white mode! Not cool at all

Hi there,

Thank you for your report!

I was able to reproduce this issue, and I have flagged this to our engineering team.

[ivan-ivanov-sciant]

Uninstalling and installing again the flatpack doesn't resolve the issue for me, too. Currently, I was able to run on the black theme after uninstalling the flatpack and installing the Debian pack - Bitwarden-2023.10.1-amd64.deb.

[darkBuddha]

reinstalling fixed it for me, but also the version changed (2023.10.1 works)

After Installing the latest version manually (dpkg -i .deb) it worked again

If you are using flatpak, try downgrading using the following command:

sudo flatpak update --commit=d484e7474b902fb30a39acafd054b2027cf6ec4acca65266319e517a9fdce902 com.bitwarden.desktop

Running this was the only way to restore the rendering.

System:
Kernel: 5.15.0-89-generic x86_64 bits; Distro: Linux Mint 21.2 on Cinnamon 5.8.4

Occurred for me in both light and dark mode. Removing the app data directory seemed to resolve, so perhaps it’s some bad cache data.

For Flatpak, it was under ~/.var/com.bitwarden.desktop. Clearing the cache didn't solve the issue, and only worked after I cleared the entire directory.

If you clear the cache, it will generate the following errors:

Errors:

Considering this bug is rendering related, I'm wondering how much of it is due to some deployment issue.

Reinstalling did not work for me, but removing the app data did.
Using AppImage on the latest version of Fedora Wayland.

When it was not working the app's display was completely blank, but I was:

• able to login (blinking cursor in password field).
• able to launch Inspect Element (although that was also blank -- nothing was visible, but I could hover over & click on elements).
