I'm using awesome wm with a pretty stock config, just added a picom auto startup.

picom version

Steps of reproduction

  1. Install https://github.com/yuk7/ArchWSL and follow the instructions given
  2. Install https://sourceforge.net/projects/vcxsrv/
  3. In wsl add export DISPLAY="grep nameserver /etc/resolv.conf | sed 's/nameserver //':0" to your .bashrc
  4. restart wsl by using exit & wsl --shutdown and enter wsl again.
  5. use echo to view the display variable for me it is : 172.26.176.1:0
  6. Install awesome , picom, xterm and ttf-opensans using pacman
  7. start a vcxsrv instance in windows using: .\vcxsrv.exe -clipboard -primary -fullscreen -ac
  8. run awesome using awesome&
  9. run picom with --backend xrender
  10. In the vcxsrv server window using the mouse test the top bar and try opening a terminal with right click.
  11. kill the picom process
  12. run picom with --backend glx
  13. Repeat step 10 and observe the issues described in the following sections.

Expected behavior

Current Behavior

Along with the visual glitches. Is the UI also non repsonsive mainly the top bar does not update when clicken works pace buttons. But awesome does preform the expected function under the hood. image

absolutelynothelix commented 1 year ago

afaiu in your case a software rasterizer is used (i.e. rendering is done on cpu using maybe llvmpipe, not on gpu using it’s driver) and there is #1030, but it’s not clear if these are driver issues or picom can be improved.

and if my guess is right and llvmpipe is used --legacy-backends --backend=glx may work for you.

why people always try to run picom in such funky configurations 😩

The glxinfo says it's using D3D12 not llvmpipe or that something different? I get these erros when using the flags you suggested:

Disabling vsync fixed those errors, I'm closing this issue. Thanks for your help @absolutelynothelix !

absolutelynothelix commented 1 year ago

i don't like that picom segfaults in your cases. can you post the backtrace if it's possible? (i remember that last time i tried to obtain a backtrace in wsl it was impossible or something)

upd: from your original post it seems that even glxinfo segfaults, so i believe the segfault is happening somewhere in the driver but a backtrace from picom would be useful if it's an error on our side

The glxinfo says it's using D3D12 not llvmpipe or that something different?

i'm not exactly sure how wsl does graphics but it behaves just like llvmpipe

80sVectorz commented 1 year ago

I made another one: picom.2.zip

absolutelynothelix commented 1 year ago

i’m afraid i won’t be able to open a coredump from wsl on usual system, but i’ll try tomorrow. if it’s possible for you to open it in gdb, do bt and post the backtrace you recieve?

80sVectorz commented 1 year ago

How would I open the .trace file in gdb?

absolutelynothelix commented 1 year ago

i was takling about coredumps. from the last line of output you provided picom segfaults (terminated by sigsegv), so it should generate a coredump somewhere. i’d like to look at backtrace of this coredump if it’s possible.

this may be useful: https://github.com/yshui/picom/wiki/Reporting-issues#get-a-stack-trace

if you’re unable to provide a backtrace for some reason (it’s may be tricky in wsl), don’t worry, that’s ok.

I could not find a core dump in the place I found online.

yeah, as i said, it may be tricky in wsl. that's ok, don't worry.
