What I did / Reproducing =========================== It happens when I use Easystrokes to emulate `Ctrl+F4` or `Ctrl+PageUp/Down`. So far it happened about 5 recognized times, 3 recorded within the last 3(?) month. twice during tab switching in incognito Firefox and once in VSCode. Reproducability ================ I feel it's very consistent in crashing in Firefox incognito. But it's not purposely reproducible 100%. I would give more information, but the stacktrace of the crashdump does not tell much. I installed debug symbols for xorg, but they made no change viewing it. Here is the (obscured) stack trace: ``` Reading symbols from /usr/lib/xorg/Xorg... Reading symbols from /usr/lib/debug/.build-id/c1/54f39135c0adc1b59f5b6dd49a73301b4311c8.debug...
