Segmentation fault (core dumped): Cannot create EGL context: invalid display (last error: EGL_SUCCESS)

まず、報告された Mint、X11、NVIDIA の構成で xreader を起動したときのクラッシュを再現し、その後、起動処理中に発生する EGL 初期化の失敗を追跡します。無効な EGL display によって segmentation fault が発生しなくなり、アプリケーションが起動の失敗を安全に処理できれば、修正は完了です。

Expected behavior

Not a segmentation fault ;-)

Additional information

I have a gut feel this will come good with reboot. In short, I have recollection of it happening before and finding that. I'm on 24/7 box though and rebooting is not a simple thing, so not tried it this time yet. In part because it's not a relevant qualifier of bug status (it's a bug regardless) but might point to a cause (put it in the camp of configs). So if it's helpful an amateurishly redacted env:
