How to redraw labels of plasma desktop icons in folder-view mode using a custom script
Hi,
I'm currently using Debian Buster with the latest updates on a
computer equipped with a nvidia graphic card (GeForce 9600M GT) using
latest legacy nvidia proprietary drivers (340.107).
The labels of plasma desktop icons in folder-view mode are always
corrupted after resume from suspend to memory or hibernation to disk.
This bug has been already reported in the KDE Bugtracking System as
"closed upstream" [0][1] but in my current hardware configuration it
is still there (I've opened a bug report [2] with the details about
graphic card driver).
According to [1], the nvidia proprietary driver should expose a
property called GL_NV_robustness_video_memory_purge and the
recognition of this property seems has been be implemented in the
latest QT version after bugs reports [0][1]. Unfortunately, the
current legacy nvidia driver for GeForce 9600M GT (version 340.107)
seems not to implement this property, as shown by the glxinfo command
in my computer. Therefore, I suppose that this bug will be not solved
neither upstream (kde/qt) nor by the nvidia developers.
I would like to implement a workaround to redraw plasma-shell desktop
icons in folder-view mode. I don't want to force-restart plasmashell
after every resume from suspend/hibernate as suggested in [3], because
it takes time for the restart and the plasmashell rendering is not
always correct.
Therefore, I would like to use, for example, a ECMA script to send a
message by dbus to plasmashell to redraw its contents. I've read KDE
documentation about Plasma Desktop Scripting [4], but I wasn't able to
figure out how to do it as a ECMA script and your help would be
appreciated.
Thanks in advance,
