i also tried:

• --in-process-gpu flag
• export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libstdc++.so.6
• sudo apt install libgl1-mesa-dri none of that helped

also the appearance of the app version from "Help" -> "About Bitwarden" is broken: however, the right button correctly copies version info to the clipboard

Issue Tracking Info

• [X] 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.

Thank you for reporting this issue! We've added this to our internal tracking system. ID: PM-13735

@belous-dp This might be a duplicate of https://github.com/bitwarden/clients/issues/2628

@djsmith85 I don't think it's a duplicate, or rather the blurryness isn't. I don't know about the font issue. The blur is more likely due to electron (and thus bitwarden) using Xwayland by default. Xwayland works rather poorly with fractional scaling, scaling up the lower resolution image, resulting in a blurry image. This PR https://github.com/bitwarden/clients/pull/10359 fixes it by defaulting to Wayland and only falling back to X or Xwayland when overwritten by an env variable or when wayland is not available.

However there is a bug in electron right now, which prevents the PR from being merged.

@belous-dp Could you try the snap or appimage from https://github.com/bitwarden/clients/actions/runs/10809683171?pr=10359 to see if the blur is gone for you?

Adding the args doesn't work because prior to the PR, the electron builder config for snap does not contain "allowNativeWayland": true.

[belous-dp]

@quexten thanks for your detailed response! got it.

• .deb package works fine, UI scaling is ok, font issues resolved
• AppImage works fine (after installing libfuse2) -- no blurriness, no font issues
• for .snap package (after installing it with snap install pckg.snap --dangerous), UI scaling is fine, but the 'About' font issue isn't resolved. anyway, the latter is insignificant because fonts across other parts of the app display correctly

[quexten]

Nice, thank you for testing. I hope the electron bug that blocks merging the change gets fixed soon.

The font issue is a different issue and tracked in the ticket that @djsmith85 linked above.
