sounds like you're using a small cl_crosshair_scale. I play on 640x480 so I have the same thing. I usually go for something like 20 to 25.5

Try larger crosshair sizes. What can also help is using .5 at the end. Like try "cl_crosshair_scale 20.5" if 20 looks bad

Aside from that the only solutions are:
*using a higher resolution
*editing the VTF yourself until it looks right on your prefered crosshair scale. For this I recommend using a VTF plug-in with paint.net/gimp/photoshop. Editing them is easy once you know what you're doing (it's all I do these days) but if it's just for this crosshair I'd mess with scale instead
*PM me with your 4:3 resolution and i'll make some alternate versions that hopefully looks better (no promises on this being soon. my exams start this Monday until September 5th)

Just to make sure I made my own version of Thalash Seeker using Leth's Seeker as a base (recolored the dot green, kept the wings white)

Like Jynxii pointed out you need to have your crosshair color settings on full white as well (this preserves the colors of the VTF). So try that first. If you set your current Seeker to white and it goes full white then replace it with mine (rename mine to Seeker and throw it in the Thumbnails folder)

download links in those threads. Your options:
HUD crosshairs
If your custom HUD already has a seeker crosshair, enable it, then use crosshair5 in-game.
If not there's instructions and downloads in the threads for installing a custom font with the seeker crosshair in it

VTF crosshairs
very easy if you've worked with VTF crosshairs before. Download to VTFs also in those threads
If you're not familiar with these it can take a bit to figure out but I can recommend using something like Leth's crosshair pack as base or cfg.tf's crosshair pack maker. you just have to switch around the files' name so it uses Thalash' crosshair instead

edit: Archie's post below should work. Follow his instructions. It's the VTF crosshair method I wrote about. You then have to use the command cl_crosshair_file "" in console (or go to Options > Multiplayer > Crosshair None)

estimating 400, though that includes this one. I also make many crosshairs from scratch so there's some v1/v2/v3 or invert/shadow/outline variations as well

Better estimate would be around 100 useable unique crosshairs

Here's 5 different versions

Only weird dreams I remember are ones from when I was around 10.

Me and my family being crushed by a dinosaur stampede. That was an interesting one. Not sure how that came to be but I think the dream started with me getting a pet triceratops and suddenly a lot more turned up

Used to have dreams of me falling off of skyscrapers at least once per week. Luckily that stopped but had at least 10 of those in a relatively short time

#1 weirdest dream is one I wrote about before in a similar thread (irrational fears thread a couple months ago maybe?):
I used to collect plush animals as a kid. Had a lot of them. One of them was a penguin about 1:1 size to an emperor penguin. In the dream it came to live and its tongue was a cobra. It cornered me in my room and the cobra tongue kept biting me while I screamed for help. It felt like I was feeling actual stinging pain and I was unable to wake up from this dream. The previous dreams I mentioned made me wake up. Not an option with this asshole though. Had that dream for a couple of days in a row so it started to worry me. Locked the penguin in a box, put the box in the attic. A while ago we were cleaning up the attic. Found the box and that penguin went straight to the trash

It is a technical issue due to them having removed over 30 posts (30 posts per page). This causes a bug with the newest page

if this is the case then contact me, phorophor. I'll more than gladly take the blame for this

I apologise for this. I have edited the comment to include this tweet. i shouldn't have taken other peoples' words for truth without an direct statement from nursey or phorofor

(not trying to move the blame away from me by saying I heard it from others. It is up to me to make sure I don't make mistakes like this. I take full responsibility for this)

edit: I guess this started the rumor by someone misinterpreting this tweet
