Error in LazPaint while cut /copy an area
« on: November 24, 2020, 07:55:33 pm »
Hi, nice app, but in Linux (LM20 based on Ubuntu 20.04), cut or copy an are would not work.

Error

$ lazpaint --sync
WARNING: TGtk2WidgetSet.InvalidateRect refused invalidating during paint message: TBGRAVirtualScreen
The program 'lazpaint' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 200473 error_code 3 request_code 18 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
 
Steps to reproduce:

1. open an image
2. select area tool
3. make an selection in the image
4. press control-X or control-C
5. program terminates, error in CLI is present

Hello and thanks for reporting the problem.

The InvalidateRect error is minor and does not cause crash. So that's probably something else.

I cannot reproduce the crash on Linux Mint 20 on 64 bit with LazPaint version 6.4.1 and 7.1.5.

It would help to have more information on the crash you get. Do you have a 32 bit or 64 bit processor?

Hi !

Just downnloaded  lazpaint7.1.5_linux64_no_install.tar to check that error.
I did not come so far as tobiast.

Startet LazPaint from the konsole, short flash and the app was gone and left this messages:

Strange thing:
If I start LazPaint as root then everything is fine.

@winni:
I have encountered the same error message and it was related to SVG files with text with the image browser. I have fixed that on dev. Is it this problem? Does the dev version work for you?

This link  :o

I was asking if you went into the image browser and had SVG files in it. And if the problem is solved with dev branch.
