I have the same problem when using DrawText: uses LCLIntf,LCLType; procedure TForm1.FormPaint(Sender: TObject); var s: String; r: TRect; begin s := 'xyzjkyg'; r := rect(0,0,width,height); DrawText(Canvas.Handle, pchar(s),length(s), r,DT_NOPREFIX or DT_SINGLELINE or DT_VCENTER or DT_END_ELLIPSIS); end; although canvas.TextRect(rect(0,0,width,height),100,100,s); works |

@CudaText man_ Is you graphic subsystem XOrg or Wayland? i've seen text cropping in GTK2 on Debian 11 Wayland. |
|
|
Mine is XOrg |
|
|
Can not reproduce on Debian 10.7, Xorg, Intel® HD Graphics 520 (Skylake GT2) Package: libgtk2.0-0 Version: 2.24.32-3 Здымак экрана, 2021-01-15 11-24-20.png (29,998 bytes) |

Mine is X.Org. |

@Alextpp @BeniBela gtk2 version? Xorg driver vendor? Did the host was restarted after last updates/upgrades (maybe fontcache corrupted)? If explicitly calling SelectFont before DrawText helps? If changing font from default helps? |

I have an RTX 2060 > If explicitly calling SelectFont before DrawText helps? Like this? SelectObject(canvas.handle, font.handle); No > Did the host was restarted after last updates/upgrades (maybe fontcache corrupted)? I restart it every day > If changing font from default helps? No At first the font size seems to help. But probably it always cuts off 2 or 3 pixels and those pixels have less impact at bigger size 1.png (25,701 bytes) arial.png (1,899 bytes) arial-2.png (23,645 bytes) 0.png (7,251 bytes) |

It looks like rectangle is of proper size, but text shifted down 2 pixels. Maybe these problems already fixed in trunk |
|
|
The DrawText issue also happens in trunk |

What font is default in your desktop? If explicitly specified 'Arial' or 'FreeSans' reproduce the problem? |
|

>What font is default in your desktop? Noto Sans, 12 >If explicitly specified 'Arial' or 'FreeSans' reproduce the problem? Yes. the third/forth picture above are arial |

The bug appears in gtk2 not in qt5 on same system Tested on Linux Mint 20 Ulyana x86_64 Mate dektop Screenshot QT5.png (18,346 bytes) Screenshot GTk2.png (16,061 bytes) |

Do removing DT_VCENTER flag helps? |
|
|
No Adding DT_NOCLIP helps, but I need clipping since the text might be wider than the box. (too bad there is no H-CLIP only option to disable V-CLIP) |
