After update from x11-misc/xscreensaver-5.45-r4 to x11-misc/xscreensaver-6.01-r3 all GL screensavers are crashing with SIGABRT and wiat a message similar to:

$ /usr/lib64/misc/xscreensaver/glslideshow
glslideshow: eglCreatePlatformWindowSurface failed: window 0x4800002 visual 0x24
Aborted (core dumped)

Non-GL screensavers (e.g. xmatrix) are not affected. If GL a screen saver comes up in DE it just shows a red print such as "glslideshow crashed with SIGABRT".

I only managed to get a semi-meaningful backtrace without debug symbols:

$ gdb

It probably is relevant that I'm using x11-drivers/nvidia-drivers-390.144 (not the latest driver, but still supported by NVIDIA and Gentoo). I found this thread on Arch Linux forums, it seems to describe a problem just like mine: https://bbs.archlinux.org/viewtopic.php?id=266841. There's also a bug report: https://bugs.archlinux.org/task/71123 and a thread on NVIDIA forum: https://forums.developer.nvidia.com/t/390-143-eglcreateplatformwindowsurface-causes-bogus-egl-bad-display-error/179820.

Since this problem doesn't seem to have a simple solution, would it be possible to at least restore x11-misc/xscreensaver-5.45-r4, as it seems it's already been deleted?

Greetings,

I can confirm this issue with some additional info; It seems it might be an issue with the current change in XScreenSaver to prefer EGL over GLX.

I just downloaded the latest source for version 6.0.2 from https://www.jwz.org/xscreensaver/ and configured with the following:

~/build/xscreensaver-6.0.2/xscreensaver-6.02 # ./configure --prefix=/usr --with-elogind --with-pam --with-gl --with-glx --with-pixbuf --with-xft 

Then, I ran `make && make install`, and now the GL screensavers are working as expected.

I hope that helps.

@arcctax: I am also running the 390.144 driver from NVidia.

HTH.
