Oh, this was a really nasty bug to reproduce. I'm not sure why - it's very simple - I guess I've only just seen screenshots of it, and never sat down to try myself. Reminder to actually report your bugs folks! In this case: 1. Place down three down three monitors and then a computer. 2. Display something on the monitor (monitor left paint a) is my go-to. 3. Break the middle monitor. We'd expect the left most monitor to be cleared, however it actually preserves the monitor contents, resizing (and skewing it) to fit on its new size! This is because we clear the server monitor, but never sync that over to the client, so the client monitor retains the old contents. To fix that, instead of nulling out the server monitor, we null out the underlying Terminal. This causes the change to be synced, fixing the bug.

CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles and more to the game. A fork of the much-beloved ComputerCraft, it continues its legacy with improved performance and stability, along with a wealth of new features.
CC: Tweaked can be installed from CurseForge or Modrinth. It runs on both Minecraft Forge and Fabric.
Contributing
Any contribution is welcome, be that using the mod, reporting bugs or contributing code. If you want to get started developing the mod, check out the instructions here.
Community
If you need help getting started with CC: Tweaked, want to show off your latest project, or just want to chat about ComputerCraft, do check out our forum and GitHub discussions page! There's also a fairly populated, albeit quiet IRC channel, if that's more your cup of tea.
We also host fairly comprehensive documentation at tweaked.cc.
Using
CC: Tweaked is hosted on my maven repo, and so is relatively simple to depend on. You may wish to add a soft (or hard)
dependency in your mods.toml
file, with the appropriate version bounds, to ensure that API functionality you depend
on is present.
repositories {
maven {
url "https://squiddev.cc/maven/"
content {
includeGroup("cc.tweaked")
includeModule("org.squiddev", "Cobalt")
}
}
}
dependencies {
// Vanilla (i.e. for multi-loader systems)
compileOnly("cc.tweaked:cc-tweaked-$mcVersion-common-api:$cctVersion")
// Forge Gradle
compileOnly("cc.tweaked:cc-tweaked-$mcVersion-core-api:$cctVersion")
compileOnly(fg.deobf("cc.tweaked:cc-tweaked-$mcVersion-forge-api:$cctVersion"))
runtimeOnly(fg.deobf("cc.tweaked:cc-tweaked-$mcVersion-forge:$cctVersion"))
// Fabric Loom
modCompileOnly("cc.tweaked:cc-tweaked-$mcVersion-fabric-api:$cctVersion")
modRuntimeOnly("cc.tweaked:cc-tweaked-$mcVersion-fabric:$cctVersion")
}
When using ForgeGradle, you may also need to add the following:
minecraft {
runs {
configureEach {
property 'mixin.env.remapRefMap', 'true'
property 'mixin.env.refMapRemappingFile', "${buildDir}/createSrgToMcp/output.srg"
}
}
}
You should also be careful to only use classes within the dan200.computercraft.api
package. Non-API classes are
subject to change at any point. If you depend on functionality outside the API, file an issue, and we can look into
exposing more features.
We bundle the API sources with the jar, so documentation should be easily viewable within your editor. Alternatively, the generated documentation can be browsed online.
