Package: rss-glx
Version: 0.9.1-6.3+b1
Tags: patch
On certain hardware and with specific X11 windows (such as the TDE lock
screen), the RSS-GLX hacks no longer display after upgrading to Bookworm from
Bullseye. This was traced to a missing glFinish() call prior to
glXSwapBuffers(); likely the AMD GPU driver has not completed rendering prior
to the Swap call, leading to the hack output not showing up on the target
window.
I have attached a patch that is confirmed to fix the issue. If desired, I can
do an NMU to include this simple fix. Ideally, this would also be backported
to Bookworm, and I can handle the backport for that as well if desired.
