I checked mesa in piCore64 and that doesn't provide libglapi either.

I'd guess that the functionality provided by libglapi has been moved elsewhere - a quick way to check would be to re-create libglapi with symlinks to libGL, run ldconfig and try again.

Otherwise, when I get a moment, I'll recompile meld against the new mesa and see what happens.

It's a long shot, but maybe xfe uses a libX* that is no longer loaded to speed things up - I took out Xorg-7.7-lib from the dep chain, maybe you could load it and try again?

It might also be good to check that 3d hardware acceleration is working (if that's what you're using)?

Hi Juanito. I'll give that a try and will report back.

I just recompiled xfe and there was no change in speed.

When xfe is starting, since the refactoring of the graphics packages strace shows me nearly 58,000 lines that start with "wait4". These lines look like this:

Does this suggest anything to you?

I have an AppImage that I created from xfe years ago. It still works and is lightning fast. I'll be using it for the time being, but am interested in debugging this and eventually getting back on the repo version of xfe.

I'll check those. Thanks for your input.

Loading Xorg-7.7-lib did not help xfe open any faster.

I do use hardware acceleration for some things (e.g., 3d screensavers, x264 decoding in mpv) but I don't think xfe uses any acceleration.
