7.6 - pinentry-qt* crashes my X session

I use pinentry-qt with GPG agent on my OpenBSD machine. This
setup worked flawlessly before I upgraded to 7.6. Now, whenever
it would be used to display password prompt, my X session crashes
and I'm back on xenodm login screen. Tried this with both
pinentry-qt5 and pinentry-qt6 and result is the same.

Here's what I found in my xsession error log:

assertion "ret != inval_id" failed: file "/usr/xenocara/lib/libX11/src/xcb_io.c", line 626, function "_XAllocID"
XIO: fatal IO error 4 (Interrupted system call) on X server ":0"
