This is likely caused by the temporary fix in version 1.90.1 on the snap package that switched the OpenGL backend to software emulation in order to prevent the crashes reported with version 1.90.0 in #212494 . If it is related, your options for now are mentioned in this comment: https://github.com/microsoft/vscode/issues/212494#issuecomment-2168072242 Hope this helps!
