Summary0003072: glPoint used for projectile rendering on minimap breaks on ATI
DescriptionATI suffers from bug of random glpoint size (no matter what pointsize is set to).

This often causes minimap to be filled by big circular blobs unless you disable minimapdrawprojectiles.

Would it be possible to use something else than glPoint to render projectiles?

 Not a duplicate abma.
Its a separate issue.

The other ticket is about start pos - which is a widget and can be changed (fixed in ZK).

This is projectile rendering, inside engine and cannot be fixed by mod.

 it looks like the cause (driver bug / spring does something weired) is the same => duplicate...

"which is a widget and can be changed" => imo a workaround, not a fix.


can you give more info / a screenshot?

how was it fixed in ZK?

 It was fixed by not using glPoint.

There is no fix to it, its a driver bug. Only way to fix it 100% reliably is to avoid using glPoint.

No other way exists, because external applications can leave driver in broken state.

 Thats irrelevant. The bug is random. It does not help to set it to anything afaik.

I tried with disabled smoothing and its still hapenning.

The driver switches between 3 states

1) normal (sizes match pointsize)
2) crazy big (sizes about 60 pixels always)
3) crazy small (sizes awlays 1 pixel)

It can be crazied by external applications -for example steam, utorrent.
Crazy mode 2 can be turned to crazy mode 3 randomly - for example by tweaking enabled widgets, disabling chili minimap etc.

 can you check if jk's recent commit improved it?

http://springrts.com/dl/buildbot/default/develop/88.0.1-182-g0058805/


the workaround is enabled when ATIHacks is enabled and GLSL is available.

see https://github.com/spring/spring/commit/87e9dbedf1a1a943da2e6d49c2dc9e0a2f7f4237
