For eglfs we have a solution for device / device-family specific
work-arounds, they're the QEglFSHooks, in
src/plugins/platforms/eglfs/qeglfshooks.h
beforeSwapBuffers() and/or afterSwapBuffers() could be added to the
hooks for instance, so that you could put your work-around in a file
specified by a custom mkspec.
As an example, ee mkspecs/devices/linux-rasp-pi-g++ for the hooks used
on the raspberry pi, qeglfshooks_pi.cpp, enabled by setting the
EGLFS_PLATFORM_HOOKS_SOURCES variable in the qmake.conf in the same
directory.
