Hello, thanks for report. We test it on Win 10 and Linux Ubuntu and it works. Can I ask you to try it also in PrusaSlicer 2.5.0-rc1 ?

[rrroonn]

Just downloaded Version 2.5.0-rc1+linux-x64-GTK3

Same issue exists.

Maybe this might help?

I have a core dump file if that helps.

Just for completeness, I also tried PrusaSlicer-2.5.0-rc1+linux-x64-GTK2-202208191500.AppImage - same issue.

Do you know last PS version, which works for you?

[rrroonn]

Sorry, no, I have not printed in the past year or more and only recently started printing again. Last time I printed I was using Windows 10 but have since migrated to Linux Mint.

Hi. We tested it with the same software setup - Linux Mint, same kernel version and gtk libs versions, but we could not reproduce it.
However, from your log it is clear that the crash originates in i965_dri driver, and there is a known issue with some intel mesa drivers and variable layer height: #7274 .
This problem will be solved in 2.6 release, in the meantime please use one of the custom builds mentioned in the issue, or you can build & try the current master.

[rrroonn]

Thank you. Glad its being sorted out.

In issue #7274 community has tested on experimental branches this issue. OpenGL 3.3 looks stable and it is fixed in 2.6.0.
So, I close this issue. Thank you
