First vertical split since launch loses syntax coloring

[cplir-c]

On the new june build of corrosion (1.2.1.202106081156) and eclipse 2020-12 doing Window -> Editor -> Split Editor (Vertical) for the first time since eclipse launch on a 200 line rust file results in the second pane consistently being uncolored. It also happens when I leave the vertical split open and restart eclipse.

I noticed the same issue today.

Eclipse Version: 2021-06 (4.20.0) Corrosion: 1.2.1.202106081156

Do you still face this issue with latest version?

[hydra]

@akurtakov I switched to using CLion for rust development. I don't have enough free time to follow up on this, maybe @cplir-c can test it?

The first vertical split since launch looks to color properly, but if I leave a vertical split open and restart eclipse the right pane isn't colored. I was testing using a 200 line, 100 line, and 30 line rust file and they all worked similarly.

If I open a vertical split on my cargo.toml file though, it doesn't color even if I don't restart Eclipse.

If I close and reopen the vertical split, it syntax colors. Tested with my cargo.toml and a 30 line rust file.

eclipse version: Version: 2022-06 (4.24.0) Build id: 20220609-1112

corrosion version: Corrosion: 1.2.4.202206282034

I had installed eclipse-cpp using the eclipse installer and downloaded corrosion from the eclipse marketplace.

I couldn't reproduce on my Fedora workstation. Can you please share details about your environment? And maybe share some files and details to reproduce the issue from a fresh workspace?

Hi, I just tried this again today, the color now appears on the pane on the right, but if the IDE is them restarted, the pane on the right is uncolored.

Here's the short details of my installation:

Here's the full details of my installation: log.txt

I started with the latest CDT package, and then installed other plugins and features afterwards.

Here's a screenshot of the issue:

Here's the workspace: 4.24-rust-corrosion-378.zip

Here's the demo project the workspace uses, which is just a new cargo project, and also contains the eclipse project and settings for it: hello-world.zip
