User interface does not show up if using OpenGL Renderer

[sebescudie]

Environment

• OS: Windows 10 21H2
• Version: 1.9.13
• GPU: Nvidia RTX A6000, drivers are up to date

Describe the bug
This is a very weird one, as I have seen it happening on some machines and not on others. When starting Châtaigne, the user interface simply does not show up. You can only see the menu bar and the tooltips when you blindly hover something. See the following video capture.

Expected behavior
Would expect the UI to show up :-)

Additional context
Managed to get it working by manually copying a Chataigne.settings file from another (working) machine on which I had disabled Use OpenGL Renderer in the Preferences section.
In other words, it looks like when the UI is using the OpenGL renderer, some machines do not display the user interface at all. For the record, same behavior can be observed with Blux on the same machine.

I also took the oportunity to enable logging in the settings before moving them to the faulty machine, but the logs don't show anything special regarding the UI not working.

Interesting. Should openGL be disabled by default ?

Would be great to debug on this computer to see if there is an error raising that we can catch to disable OpenGL automatically

Had a look at Windows' event log as well but could not see anything related to this error, will double-check next week. Also, if you think about something specific to look for, please let me know and I'll have a look :-)

When you say "debug", do you mean running Châtaigne from source to see if something shows up in VS?

[benkuper]

yes running from source :)
In case this happens again, you don't need to find a Chataigne.settings files, you can specify -forceNoGL to avoid using openGL
