Cutter freezes when scrolling disassembly #3328
Comments
|
If you scroll at moderate speed do you see a bunch of warnings in the builtin console widget? |
log:also now i'm not so sure that wayland is related, i'm now getting freezes in X when trying to open the same executable again. backtrace:the application freezes there. |

Ok this looks like combination of two problems:
|
|
I cannot reproduce it on Debian. And the PCRE2 and NixOS issues don't mention problems with JIT anywhere. |
|
@praschke Setting up NixOS takes pretty long for me (installing qt6/5 doesn't work and more). And I don't know unfortunately, when I will find time to take care of it. So if you are willing, you can test the following patches, which disables JIT for the regex engine. If they do work, it means NixOS has problems with the PCRE2 JIT as well. We shoud report this in NixOS/nixpkgs#300056 in this case. And than see how they'd like to solve it. Diffs They are for diff --git a/meson.build b/meson.build

Environment information
Describe the bug
Scrolling too quickly in the disassembly freezes Cutter.
To Reproduce
Steps to reproduce the behavior:
