QXcbConnection: XCB error: 3 (BadWindow)

[jonasstein]

After loading a large document I receive

QXcbConnection: XCB error: 3 (BadWindow), sequence: 3045, resource id: 19752800, major code: 40 (TranslateCoords), minor code: 0

on stdout/stderr. How can I collect the required information to trace the problem?

TeXstudio 2.12.8 (hg n/a)
Using Qt Version 5.9.4, compiled with Qt 5.9.4 R
Running on Gentoo Linux, Mate 1.18 Desktop.

Update: Added Systeminformation

echo $XDG_SESSION_TYPE # tests, if wayland, or x11 is running
x11

no feedback

unless it is reproducible, there is nothing we can do.
(and I strongly susüect that gentoo is the culprit)
