SUMMARY

Whenever I drag on a highlighted string of text in a file with a lot of stuff in it, a big black rectangle appears, which spans across both of my monitors. The following appears in journalctl:

```
Feb 04 19:01:54 compooter kwin_wayland[2626]: 0x3: GL_INVALID_VALUE in glTexStorage2D(invalid width, height or depth)
Feb 04 19:01:54 compooter kwin_wayland[2626]: 0x3: GL_INVALID_OPERATION in glTexSubImage2D(invalid texture level 0)
Feb 04 19:01:54 compooter kwin_wayland[2626]: 0x3: GL_INVALID_OPERATION in glTexSubImage2D(invalid texture level 0)
```

STEPS TO REPRODUCE
1. Open Kate 
2. Create a new file
3. Put a lot of text into it
4. Highlight a string of text and drag it

OBSERVED RESULT

A big black rectangle appears when dragging the text

EXPECTED RESULT

Text appears as it should - like it does when there is not a lot of stuff in the text file.
