No text after opensuse 20231026 update

I have checked the troubleshooting

Bug report

After latest updates to openSUSE Tumbleweed, Inkdrop starts but no text is displayed anywhere in the interface. As shown in screenshot below:

The unique error messages that I captured from the console are:

[5037:1028/174336.107568:ERROR:shared_context_state.cc(81)] Skia shader compilation error
[5002:1028/174336.326310:ERROR:nss_util.cc(357)] After loading Root Certs, loaded==false: NSS error code: -8018
[5037:1028/174342.591848:ERROR:gl_surface_presentation_helper.cc(260)] GetVSyncParametersIfAvailable() failed for 3 times!

The messages appear many times, but these are unique samples.

Environment

Platform: opensuse-tumbleweed gnome desktop
Platform version: 20231026
App Version: inkdrop-5.6.0-1.x86_64.rpm

How to reproduce

Just start the app.

Note, Inkdrop ran fine on the previous versions of openSUSE since I started using Inkdrop.

FYI: what to do in case of "Skia shader compilation error" reports on the terminal (Linux)

### Your issue I updated my libdrm yesterday and rebuilt Mesa after that. Af…ter retarting Ferdium this morning I got rendering issues and endless error messages on the calling terminal: ``` xdg-settings: unexpected/missing argument Try 'xdg-settings --help' for more information.

Hi Takuya,

I don’t know as I don’t use chromium.

openSUSE is a rolling release linux and could have shipped a very new library that Inkdrop doesn’t like.

Inkdrop worked before the latest update and continues to run fine on Debian 12.2

craftzdog · October 30, 2023, 1:21am

Inkdrop (Electron) is a chromium-based app. You can try clearing GPUCache and please let me know if it works.

Jim_Connor · October 30, 2023, 2:50am

Does that mean deleting all files in:
~/.config/inkdrop/GPUCache ?

craftzdog · October 30, 2023, 3:27am

Yes.

Jim_Connor · October 30, 2023, 3:51am

That appears to have resolved this issue.

I’ll let you know if I see any other odd behaviour.

Thanks for your quick responses.

I makes me feel good about continuing to use Inkdrop!

Great! Thanks for letting me know.
Have a beautiful day.
