Whenever I select text (alpha channel selection) I get those left over white pixels ... Can someone help me? Did I set anything wrong?

Well, I was trying for some definite effects on a text layer. Here is what I got:
    --first try
    --second try
    --third try.
The last one gets closer to what I was after--grateful if anybody can suggest a way to improve on it.
All 3 began from a bent text (thanks, Ofnuts!) colored with a blue-to-white linear gradient, to which I applied the follwing bump map (minimun blur):
   
1. default options, depth decreased to 2
2. same, azimuth moved to nearly vertical, plus bottom 2px removed (layer mask), because of too much white
3. is 2, minus the mask and with the bump map repeated, options as in 1.

As I said, the result isn't all I wished for, being quite new to bump maps... 
Any ideas?

from GIMP documentation I understand that GIMP processes internally all in 3x32b floating point no matter what bit depth is used.

What puzzles me most - sRGB is 8bit gamma corrected and if I import 3x16b TIFF, what happens to image originally exported with ProPhoto RGB???

is sRGB just for preview and all available data 3x16b are used for processing anyway, please?

I do not know how to explain it, hopefully you understand.

I am a newbie with GIMP 2.10.12
I am trying to remove the distortion introduced by glasses
I have come across this tutorial for photoshop
Basically the way I understand it:
1. Load image on layer 1
2. Select area inside eyeglass
3. Paste in new layer 2
4. Add layer mask to layer 2
5. Stretch image on layer 2. Layer mask should "restrict" the visible area to the original glass area

Well I am not getting it to work. Sorry I am pretty sure this is basic
When I stretch the image the layer mask is not covering anything. Appreciate any assistance...

Hi there, haven't posted anything for a while. Can someone please help me. I can't seem to toggle the layers up and down so i can put thing in front or behind in the work area.

I have installed Ubuntu18.04LTS subsystem in Win10. Gimp are also installed and updated.


the gimp error messgaes:
(1) when I open gimp with the code: "export DISPALY=:0.0, gimp", an error message will be shown in the Ubuntu terminal, as shown in the below,

Failed to execute child process “dbus-launch” (No such file or directory)
(gimp:1109): GLib-GObject-WARNING **: 10:18:49.757: g_object_set_is_valid_property: object class 'GeglConfig' has no property named 'cache-size'
/usr/bin/dbus-launch terminated abnormally without any error message

(2) when I would like to read a image(gimp can not open .eps, .jpeg, but can open PDF file ) with gimp, a gimp message will appear as the following,
Opening '/home/qixycn/P1structure.eps' failed:
Permission denied

I truely hope someone can help me solve these problems. It has troubles me about a week. I'm so frustrated. Thank you in advance.

My own take on luminosity masks. While it pays its dues to PatDavid's canonical tutorial on the subject, it creates the same masks using a different and (hopefully) more efficient method that allows:

• to create a luminosity selection from the current layer in one single click (or one keystroke if you defined shortcuts)
  
• in a future version, to define your own masks

I've created a PDF portfolio using Gimp 2.10, but when I open the PDF in Acrobat, the fonts are all messed up. How can I fix it?
