Description

For reproducing, start quick minimal browser with https://plexinc.github.io/sandbox/matt/bugs/qt/select/ then open and close the drop-down list (same as https://bugreports.qt.io/browse/QTBUG-77072)

The issue is flaky so it may not assert for the first try.

In release mode, it produces an error message:

[27567:775:0806/154812.109601:ERROR:gl_bindings_autogen_gl.cc(14572)] Trying to call glFlush without current GL context

In debug mode, it asserts:

[36101:775:0806/155102.998924:FATAL:gl_bindings_autogen_gl.cc(14570)] Check failed: false. Trying to call glFlush without current GL context
