Good news:
Solved by upgrading the kernel from 4.19.48 to 4.19.136 (the latest in
the 4.19 series).
Thanks for the hint that the work on gma500 has, in a sense, come to an
end, reminding me that the latest kernel tarballs come with a long
history of bug chasing efforts.
Another strange issue has been solved with the upgrade: previously the
geeqie application worked OK, but displayed absolutely nothing. I
actually mean the two contradictory statements: "geeqie --debug 4"
traces were looking quite alike the traces from another system (other
GPU, same O/S) in a simple session (alt-F4 after loading an image);
absolutely no window was showing up from the geeqie application (with
GMA500 / kernel 4.19.48), the X11 system nonetheless keeping trace of
the current focus to this invisible window.
Thanks for making this good work available to us mortals!
